Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022138, here are decompositions:

  • 67 + 1022071 = 1022138
  • 79 + 1022059 = 1022138
  • 127 + 1022011 = 1022138
  • 241 + 1021897 = 1022138
  • 277 + 1021861 = 1022138
  • 307 + 1021831 = 1022138
  • 331 + 1021807 = 1022138
  • 379 + 1021759 = 1022138

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Thursday, January 2, 2138 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2138-02-01 (DMMYYYY (Euro, single-digit day))
  • 2138-10-02 (MMDYYYY (US, single-digit day))
  • 2138-02-10 (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 1,022,138 and was likely granted around 1912.

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