Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022900, here are decompositions:

  • 19 + 1022881 = 1022900
  • 31 + 1022869 = 1022900
  • 79 + 1022821 = 1022900
  • 103 + 1022797 = 1022900
  • 127 + 1022773 = 1022900
  • 139 + 1022761 = 1022900
  • 181 + 1022719 = 1022900
  • 199 + 1022701 = 1022900

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Saturday, January 2, 2900 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2900-02-01 (DMMYYYY (Euro, single-digit day))
  • 2900-10-02 (MMDYYYY (US, single-digit day))
  • 2900-02-10 (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 1,022,900 and was likely granted around 1912.

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