Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042660, here are decompositions:

  • 29 + 1042631 = 1042660
  • 41 + 1042619 = 1042660
  • 53 + 1042607 = 1042660
  • 83 + 1042577 = 1042660
  • 89 + 1042571 = 1042660
  • 131 + 1042529 = 1042660
  • 137 + 1042523 = 1042660
  • 173 + 1042487 = 1042660

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 4, 2660 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2660-04-01 (DMMYYYY (Euro, single-digit day))
  • 2660-10-04 (MMDYYYY (US, single-digit day))
  • 2660-04-10 (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 1,042,660 and was likely granted around 1912.

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