Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137600, here are decompositions:

  • 3 + 137597 = 137600
  • 7 + 137593 = 137600
  • 13 + 137587 = 137600
  • 109 + 137491 = 137600
  • 157 + 137443 = 137600
  • 163 + 137437 = 137600
  • 241 + 137359 = 137600
  • 349 + 137251 = 137600

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 137,600 and was likely granted around 1872.

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