Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031918, here are decompositions:

  • 7 + 1031911 = 1031918
  • 109 + 1031809 = 1031918
  • 157 + 1031761 = 1031918
  • 211 + 1031707 = 1031918
  • 241 + 1031677 = 1031918
  • 397 + 1031521 = 1031918
  • 439 + 1031479 = 1031918
  • 457 + 1031461 = 1031918

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 3, 1918 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1918-03-01 (DMMYYYY (Euro, single-digit day))
  • 1918-10-03 (MMDYYYY (US, single-digit day))
  • 1918-03-10 (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 1,031,918 and was likely granted around 1912.

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