Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042658, here are decompositions:

  • 61 + 1042597 = 1042658
  • 139 + 1042519 = 1042658
  • 277 + 1042381 = 1042658
  • 349 + 1042309 = 1042658
  • 571 + 1042087 = 1042658
  • 577 + 1042081 = 1042658
  • 619 + 1042039 = 1042658
  • 709 + 1041949 = 1042658

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 4, 2658 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2658-04-01 (DMMYYYY (Euro, single-digit day))
  • 2658-10-04 (MMDYYYY (US, single-digit day))
  • 2658-04-10 (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 1,042,658 and was likely granted around 1912.

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