Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137700, here are decompositions:

  • 41 + 137659 = 137700
  • 47 + 137653 = 137700
  • 61 + 137639 = 137700
  • 67 + 137633 = 137700
  • 103 + 137597 = 137700
  • 107 + 137593 = 137700
  • 113 + 137587 = 137700
  • 127 + 137573 = 137700

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 137,700 and was likely granted around 1872.

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