Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022656, here are decompositions:

  • 3 + 1022653 = 1022656
  • 17 + 1022639 = 1022656
  • 23 + 1022633 = 1022656
  • 83 + 1022573 = 1022656
  • 137 + 1022519 = 1022656
  • 149 + 1022507 = 1022656
  • 227 + 1022429 = 1022656
  • 269 + 1022387 = 1022656

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 2, 2656 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2656-02-01 (DMMYYYY (Euro, single-digit day))
  • 2656-10-02 (MMDYYYY (US, single-digit day))
  • 2656-02-10 (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 1,022,656 and was likely granted around 1912.

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