Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130218, here are decompositions:

  • 7 + 130211 = 130218
  • 17 + 130201 = 130218
  • 19 + 130199 = 130218
  • 47 + 130171 = 130218
  • 71 + 130147 = 130218
  • 97 + 130121 = 130218
  • 131 + 130087 = 130218
  • 139 + 130079 = 130218

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 130,218 and was likely granted around 1872.

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