Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131202, here are decompositions:

  • 31 + 131171 = 131202
  • 53 + 131149 = 131202
  • 59 + 131143 = 131202
  • 73 + 131129 = 131202
  • 89 + 131113 = 131202
  • 101 + 131101 = 131202
  • 131 + 131071 = 131202
  • 139 + 131063 = 131202

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 131,202 and was likely granted around 1872.

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