Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018772, here are decompositions:

  • 3 + 1018769 = 1018772
  • 43 + 1018729 = 1018772
  • 61 + 1018711 = 1018772
  • 103 + 1018669 = 1018772
  • 151 + 1018621 = 1018772
  • 229 + 1018543 = 1018772
  • 283 + 1018489 = 1018772
  • 463 + 1018309 = 1018772

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 1, 8772 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8772-10-01 (MMDYYYY (US, single-digit day))
  • 8772-01-10 (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 1,018,772 and was likely granted around 1911.

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

Position in π

The digit sequence 1018772 first appears in π at position 781,112 of the decimal expansion (the 781,112ordinal-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.
