Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021150, here are decompositions:

  • 23 + 1021127 = 1021150
  • 59 + 1021091 = 1021150
  • 83 + 1021067 = 1021150
  • 107 + 1021043 = 1021150
  • 131 + 1021019 = 1021150
  • 149 + 1021001 = 1021150
  • 173 + 1020977 = 1021150
  • 191 + 1020959 = 1021150

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 2, 1150 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1150-02-01 (DMMYYYY (Euro, single-digit day))
  • 1150-10-02 (MMDYYYY (US, single-digit day))
  • 1150-02-10 (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 1,021,150 and was likely granted around 1912.

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