Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047638, here are decompositions:

  • 79 + 1047559 = 1047638
  • 127 + 1047511 = 1047638
  • 139 + 1047499 = 1047638
  • 271 + 1047367 = 1047638
  • 331 + 1047307 = 1047638
  • 349 + 1047289 = 1047638
  • 367 + 1047271 = 1047638
  • 409 + 1047229 = 1047638

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 4, 7638 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 7638-04-01 (DMMYYYY (Euro, single-digit day))
  • 7638-10-04 (MMDYYYY (US, single-digit day))
  • 7638-04-10 (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 1,047,638 and was likely granted around 1912.

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