Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042600, here are decompositions:

  • 3 + 1042597 = 1042600
  • 17 + 1042583 = 1042600
  • 23 + 1042577 = 1042600
  • 29 + 1042571 = 1042600
  • 71 + 1042529 = 1042600
  • 113 + 1042487 = 1042600
  • 131 + 1042469 = 1042600
  • 149 + 1042451 = 1042600

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 4, 2600 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2600-04-01 (DMMYYYY (Euro, single-digit day))
  • 2600-10-04 (MMDYYYY (US, single-digit day))
  • 2600-04-10 (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 1,042,600 and was likely granted around 1912.

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