Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019490, here are decompositions:

  • 11 + 1019479 = 1019490
  • 19 + 1019471 = 1019490
  • 23 + 1019467 = 1019490
  • 37 + 1019453 = 1019490
  • 41 + 1019449 = 1019490
  • 47 + 1019443 = 1019490
  • 67 + 1019423 = 1019490
  • 79 + 1019411 = 1019490

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 9490 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 9490-10-01 (MMDYYYY (US, single-digit day))
  • 9490-01-10 (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 1,019,490 and was likely granted around 1911.

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