Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027940, here are decompositions:

  • 157 + 1027783 = 1027940
  • 163 + 1027777 = 1027940
  • 181 + 1027759 = 1027940
  • 223 + 1027717 = 1027940
  • 349 + 1027591 = 1027940
  • 373 + 1027567 = 1027940
  • 421 + 1027519 = 1027940
  • 457 + 1027483 = 1027940

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 7940 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 7940-02-01 (DMMYYYY (Euro, single-digit day))
  • 7940-10-02 (MMDYYYY (US, single-digit day))
  • 7940-02-10 (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 1,027,940 and was likely granted around 1912.

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