Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509172, here are decompositions:

  • 23 + 509149 = 509172
  • 71 + 509101 = 509172
  • 101 + 509071 = 509172
  • 109 + 509063 = 509172
  • 149 + 509023 = 509172
  • 199 + 508973 = 509172
  • 211 + 508961 = 509172
  • 229 + 508943 = 509172

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 509,172 and was likely granted around 1893.

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