Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044638, here are decompositions:

  • 19 + 1044619 = 1044638
  • 79 + 1044559 = 1044638
  • 109 + 1044529 = 1044638
  • 181 + 1044457 = 1044638
  • 229 + 1044409 = 1044638
  • 241 + 1044397 = 1044638
  • 271 + 1044367 = 1044638
  • 349 + 1044289 = 1044638

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 4, 4638 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 4638-04-01 (DMMYYYY (Euro, single-digit day))
  • 4638-10-04 (MMDYYYY (US, single-digit day))
  • 4638-04-10 (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 1,044,638 and was likely granted around 1912.

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