Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136742, here are decompositions:

  • 3 + 136739 = 136742
  • 31 + 136711 = 136742
  • 139 + 136603 = 136742
  • 211 + 136531 = 136742
  • 223 + 136519 = 136742
  • 241 + 136501 = 136742
  • 271 + 136471 = 136742
  • 313 + 136429 = 136742

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 136,742 and was likely granted around 1872.

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