Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018740, here are decompositions:

  • 7 + 1018733 = 1018740
  • 11 + 1018729 = 1018740
  • 29 + 1018711 = 1018740
  • 31 + 1018709 = 1018740
  • 43 + 1018697 = 1018740
  • 61 + 1018679 = 1018740
  • 67 + 1018673 = 1018740
  • 71 + 1018669 = 1018740

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 8740 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8740-10-01 (MMDYYYY (US, single-digit day))
  • 8740-01-10 (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 1,018,740 and was likely granted around 1911.

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