Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022742, here are decompositions:

  • 13 + 1022729 = 1022742
  • 23 + 1022719 = 1022742
  • 41 + 1022701 = 1022742
  • 53 + 1022689 = 1022742
  • 59 + 1022683 = 1022742
  • 89 + 1022653 = 1022742
  • 103 + 1022639 = 1022742
  • 109 + 1022633 = 1022742

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 2742 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2742-02-01 (DMMYYYY (Euro, single-digit day))
  • 2742-10-02 (MMDYYYY (US, single-digit day))
  • 2742-02-10 (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 1,022,742 and was likely granted around 1912.

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