Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018782, here are decompositions:

  • 5 + 1018777 = 1018782
  • 13 + 1018769 = 1018782
  • 19 + 1018763 = 1018782
  • 53 + 1018729 = 1018782
  • 71 + 1018711 = 1018782
  • 73 + 1018709 = 1018782
  • 103 + 1018679 = 1018782
  • 109 + 1018673 = 1018782

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 1, 8782 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8782-10-01 (MMDYYYY (US, single-digit day))
  • 8782-01-10 (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 1,018,782 and was likely granted around 1911.

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