Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022648, here are decompositions:

  • 19 + 1022629 = 1022648
  • 37 + 1022611 = 1022648
  • 139 + 1022509 = 1022648
  • 157 + 1022491 = 1022648
  • 181 + 1022467 = 1022648
  • 199 + 1022449 = 1022648
  • 271 + 1022377 = 1022648
  • 307 + 1022341 = 1022648

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 2648 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2648-02-01 (DMMYYYY (Euro, single-digit day))
  • 2648-10-02 (MMDYYYY (US, single-digit day))
  • 2648-02-10 (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 1,022,648 and was likely granted around 1912.

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