Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509018, here are decompositions:

  • 31 + 508987 = 509018
  • 61 + 508957 = 509018
  • 67 + 508951 = 509018
  • 109 + 508909 = 509018
  • 151 + 508867 = 509018
  • 229 + 508789 = 509018
  • 397 + 508621 = 509018
  • 439 + 508579 = 509018

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 509,018 and was likely granted around 1893.

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