Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515470, here are decompositions:

  • 41 + 515429 = 515470
  • 89 + 515381 = 515470
  • 101 + 515369 = 515470
  • 113 + 515357 = 515470
  • 191 + 515279 = 515470
  • 233 + 515237 = 515470
  • 239 + 515231 = 515470
  • 317 + 515153 = 515470

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 515,470 and was likely granted around 1894.

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