Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131118, here are decompositions:

  • 5 + 131113 = 131118
  • 7 + 131111 = 131118
  • 17 + 131101 = 131118
  • 47 + 131071 = 131118
  • 59 + 131059 = 131118
  • 107 + 131011 = 131118
  • 109 + 131009 = 131118
  • 131 + 130987 = 131118

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 131,118 and was likely granted around 1872.

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