Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139586, here are decompositions:

  • 103 + 139483 = 139586
  • 127 + 139459 = 139586
  • 157 + 139429 = 139586
  • 163 + 139423 = 139586
  • 193 + 139393 = 139586
  • 199 + 139387 = 139586
  • 277 + 139309 = 139586
  • 283 + 139303 = 139586

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 139,586 and was likely granted around 1872.

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