Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040628, here are decompositions:

  • 31 + 1040597 = 1040628
  • 47 + 1040581 = 1040628
  • 97 + 1040531 = 1040628
  • 107 + 1040521 = 1040628
  • 139 + 1040489 = 1040628
  • 179 + 1040449 = 1040628
  • 181 + 1040447 = 1040628
  • 241 + 1040387 = 1040628

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 4, 0628 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 0628-04-01 (DMMYYYY (Euro, single-digit day))
  • 0628-10-04 (MMDYYYY (US, single-digit day))
  • 0628-04-10 (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 1,040,628 and was likely granted around 1912.

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