Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031490, here are decompositions:

  • 7 + 1031483 = 1031490
  • 11 + 1031479 = 1031490
  • 13 + 1031477 = 1031490
  • 29 + 1031461 = 1031490
  • 43 + 1031447 = 1031490
  • 59 + 1031431 = 1031490
  • 67 + 1031423 = 1031490
  • 79 + 1031411 = 1031490

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 3, 1490 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1490-03-01 (DMMYYYY (Euro, single-digit day))
  • 1490-10-03 (MMDYYYY (US, single-digit day))
  • 1490-03-10 (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 1,031,490 and was likely granted around 1912.

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