Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042520, here are decompositions:

  • 139 + 1042381 = 1042520
  • 151 + 1042369 = 1042520
  • 163 + 1042357 = 1042520
  • 211 + 1042309 = 1042520
  • 277 + 1042243 = 1042520
  • 337 + 1042183 = 1042520
  • 379 + 1042141 = 1042520
  • 397 + 1042123 = 1042520

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 4, 2520 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2520-04-01 (DMMYYYY (Euro, single-digit day))
  • 2520-10-04 (MMDYYYY (US, single-digit day))
  • 2520-04-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,042,520 and was likely granted around 1912.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1042520 first appears in π at position 322,069 of the decimal expansion (the 322,069ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
