Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051250, here are decompositions:

  • 3 + 1051247 = 1051250
  • 73 + 1051177 = 1051250
  • 97 + 1051153 = 1051250
  • 103 + 1051147 = 1051250
  • 181 + 1051069 = 1051250
  • 199 + 1051051 = 1051250
  • 223 + 1051027 = 1051250
  • 241 + 1051009 = 1051250

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 5, 1250 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 1250-05-01 (DMMYYYY (Euro, single-digit day))
  • 1250-10-05 (MMDYYYY (US, single-digit day))
  • 1250-05-10 (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 1,051,250 and was likely granted around 1912.

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