Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131910, here are decompositions:

  • 11 + 131899 = 131910
  • 17 + 131893 = 131910
  • 19 + 131891 = 131910
  • 61 + 131849 = 131910
  • 71 + 131839 = 131910
  • 73 + 131837 = 131910
  • 113 + 131797 = 131910
  • 127 + 131783 = 131910

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 131,910 and was likely granted around 1872.

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