Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131944, here are decompositions:

  • 3 + 131941 = 131944
  • 5 + 131939 = 131944
  • 11 + 131933 = 131944
  • 17 + 131927 = 131944
  • 53 + 131891 = 131944
  • 83 + 131861 = 131944
  • 107 + 131837 = 131944
  • 167 + 131777 = 131944

Showing the first eight; more decompositions exist.

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 131,944 and was likely granted around 1872.

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