Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518312, here are decompositions:

  • 13 + 518299 = 518312
  • 73 + 518239 = 518312
  • 79 + 518233 = 518312
  • 103 + 518209 = 518312
  • 181 + 518131 = 518312
  • 199 + 518113 = 518312
  • 211 + 518101 = 518312
  • 229 + 518083 = 518312

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 518,312 and was likely granted around 1894.

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