Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 501818, here are decompositions:

  • 127 + 501691 = 501818
  • 181 + 501637 = 501818
  • 241 + 501577 = 501818
  • 307 + 501511 = 501818
  • 367 + 501451 = 501818
  • 409 + 501409 = 501818
  • 547 + 501271 = 501818
  • 601 + 501217 = 501818

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 501,818 and was likely granted around 1893.

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