Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516122, here are decompositions:

  • 31 + 516091 = 516122
  • 73 + 516049 = 516122
  • 181 + 515941 = 516122
  • 193 + 515929 = 516122
  • 199 + 515923 = 516122
  • 283 + 515839 = 516122
  • 349 + 515773 = 516122
  • 421 + 515701 = 516122

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 516,122 and was likely granted around 1894.

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