Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045940, here are decompositions:

  • 37 + 1045903 = 1045940
  • 139 + 1045801 = 1045940
  • 211 + 1045729 = 1045940
  • 277 + 1045663 = 1045940
  • 307 + 1045633 = 1045940
  • 367 + 1045573 = 1045940
  • 397 + 1045543 = 1045940
  • 433 + 1045507 = 1045940

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 4, 5940 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 5940-04-01 (DMMYYYY (Euro, single-digit day))
  • 5940-10-04 (MMDYYYY (US, single-digit day))
  • 5940-04-10 (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 1,045,940 and was likely granted around 1912.

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