Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021950, here are decompositions:

  • 31 + 1021919 = 1021950
  • 43 + 1021907 = 1021950
  • 53 + 1021897 = 1021950
  • 71 + 1021879 = 1021950
  • 89 + 1021861 = 1021950
  • 101 + 1021849 = 1021950
  • 113 + 1021837 = 1021950
  • 151 + 1021799 = 1021950

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 1950 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1950-02-01 (DMMYYYY (Euro, single-digit day))
  • 1950-10-02 (MMDYYYY (US, single-digit day))
  • 1950-02-10 (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 1,021,950 and was likely granted around 1912.

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