Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1030778, here are decompositions:

  • 19 + 1030759 = 1030778
  • 37 + 1030741 = 1030778
  • 97 + 1030681 = 1030778
  • 139 + 1030639 = 1030778
  • 241 + 1030537 = 1030778
  • 337 + 1030441 = 1030778
  • 349 + 1030429 = 1030778
  • 367 + 1030411 = 1030778

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 3, 0778 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0778-03-01 (DMMYYYY (Euro, single-digit day))
  • 0778-10-03 (MMDYYYY (US, single-digit day))
  • 0778-03-10 (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 1,030,778 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 1030778 first appears in π at position 946,158 of the decimal expansion (the 946,158ordinal-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.
