Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042860, here are decompositions:

  • 11 + 1042849 = 1042860
  • 23 + 1042837 = 1042860
  • 31 + 1042829 = 1042860
  • 41 + 1042819 = 1042860
  • 61 + 1042799 = 1042860
  • 79 + 1042781 = 1042860
  • 101 + 1042759 = 1042860
  • 127 + 1042733 = 1042860

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 4, 2860 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2860-04-01 (DMMYYYY (Euro, single-digit day))
  • 2860-10-04 (MMDYYYY (US, single-digit day))
  • 2860-04-10 (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 1,042,860 and was likely granted around 1912.

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