Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 507818, here are decompositions:

  • 37 + 507781 = 507818
  • 61 + 507757 = 507818
  • 127 + 507691 = 507818
  • 151 + 507667 = 507818
  • 211 + 507607 = 507818
  • 229 + 507589 = 507818
  • 397 + 507421 = 507818
  • 457 + 507361 = 507818

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 507,818 and was likely granted around 1893.

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