Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131316, here are decompositions:

  • 5 + 131311 = 131316
  • 13 + 131303 = 131316
  • 19 + 131297 = 131316
  • 23 + 131293 = 131316
  • 67 + 131249 = 131316
  • 103 + 131213 = 131316
  • 113 + 131203 = 131316
  • 167 + 131149 = 131316

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 131,316 and was likely granted around 1872.

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