Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018738, here are decompositions:

  • 5 + 1018733 = 1018738
  • 29 + 1018709 = 1018738
  • 41 + 1018697 = 1018738
  • 59 + 1018679 = 1018738
  • 89 + 1018649 = 1018738
  • 179 + 1018559 = 1018738
  • 317 + 1018421 = 1018738
  • 401 + 1018337 = 1018738

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 1, 8738 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 8738-10-01 (MMDYYYY (US, single-digit day))
  • 8738-01-10 (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 1,018,738 and was likely granted around 1911.

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