Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022518, here are decompositions:

  • 5 + 1022513 = 1022518
  • 11 + 1022507 = 1022518
  • 17 + 1022501 = 1022518
  • 89 + 1022429 = 1022518
  • 131 + 1022387 = 1022518
  • 137 + 1022381 = 1022518
  • 227 + 1022291 = 1022518
  • 269 + 1022249 = 1022518

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 2518 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2518-02-01 (DMMYYYY (Euro, single-digit day))
  • 2518-10-02 (MMDYYYY (US, single-digit day))
  • 2518-02-10 (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 1,022,518 and was likely granted around 1912.

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