Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022142, here are decompositions:

  • 5 + 1022137 = 1022142
  • 13 + 1022129 = 1022142
  • 19 + 1022123 = 1022142
  • 29 + 1022113 = 1022142
  • 59 + 1022083 = 1022142
  • 71 + 1022071 = 1022142
  • 83 + 1022059 = 1022142
  • 89 + 1022053 = 1022142

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 2142 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2142-02-01 (DMMYYYY (Euro, single-digit day))
  • 2142-10-02 (MMDYYYY (US, single-digit day))
  • 2142-02-10 (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 1,022,142 and was likely granted around 1912.

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