Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 139306, here are decompositions:

  • 3 + 139303 = 139306
  • 5 + 139301 = 139306
  • 107 + 139199 = 139306
  • 137 + 139169 = 139306
  • 173 + 139133 = 139306
  • 197 + 139109 = 139306
  • 227 + 139079 = 139306
  • 239 + 139067 = 139306

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 139,306 and was likely granted around 1872.

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