Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137786, here are decompositions:

  • 43 + 137743 = 137786
  • 73 + 137713 = 137786
  • 79 + 137707 = 137786
  • 127 + 137659 = 137786
  • 163 + 137623 = 137786
  • 193 + 137593 = 137786
  • 199 + 137587 = 137786
  • 349 + 137437 = 137786

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 137,786 and was likely granted around 1872.

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