Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027442, here are decompositions:

  • 181 + 1027261 = 1027442
  • 313 + 1027129 = 1027442
  • 439 + 1027003 = 1027442
  • 463 + 1026979 = 1027442
  • 499 + 1026943 = 1027442
  • 613 + 1026829 = 1027442
  • 631 + 1026811 = 1027442
  • 643 + 1026799 = 1027442

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 7442 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 7442-02-01 (DMMYYYY (Euro, single-digit day))
  • 7442-10-02 (MMDYYYY (US, single-digit day))
  • 7442-02-10 (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 1,027,442 and was likely granted around 1912.

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