Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1031628, here are decompositions:

  • 5 + 1031623 = 1031628
  • 19 + 1031609 = 1031628
  • 67 + 1031561 = 1031628
  • 79 + 1031549 = 1031628
  • 97 + 1031531 = 1031628
  • 107 + 1031521 = 1031628
  • 139 + 1031489 = 1031628
  • 149 + 1031479 = 1031628

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 3, 1628 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1628-03-01 (DMMYYYY (Euro, single-digit day))
  • 1628-10-03 (MMDYYYY (US, single-digit day))
  • 1628-03-10 (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 1,031,628 and was likely granted around 1912.

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