Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1036638, here are decompositions:

  • 7 + 1036631 = 1036638
  • 19 + 1036619 = 1036638
  • 59 + 1036579 = 1036638
  • 101 + 1036537 = 1036638
  • 107 + 1036531 = 1036638
  • 139 + 1036499 = 1036638
  • 167 + 1036471 = 1036638
  • 179 + 1036459 = 1036638

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 3, 6638 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 6638-03-01 (DMMYYYY (Euro, single-digit day))
  • 6638-10-03 (MMDYYYY (US, single-digit day))
  • 6638-03-10 (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 1,036,638 and was likely granted around 1912.

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