Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028488, here are decompositions:

  • 17 + 1028471 = 1028488
  • 179 + 1028309 = 1028488
  • 257 + 1028231 = 1028488
  • 281 + 1028207 = 1028488
  • 347 + 1028141 = 1028488
  • 359 + 1028129 = 1028488
  • 389 + 1028099 = 1028488
  • 557 + 1027931 = 1028488

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 8488 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8488-02-01 (DMMYYYY (Euro, single-digit day))
  • 8488-10-02 (MMDYYYY (US, single-digit day))
  • 8488-02-10 (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 1,028,488 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 1028488 first appears in π at position 114,715 of the decimal expansion (the 114,715ordinal-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.
