Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495940, here are decompositions:

  • 17 + 495923 = 495940
  • 41 + 495899 = 495940
  • 47 + 495893 = 495940
  • 89 + 495851 = 495940
  • 113 + 495827 = 495940
  • 149 + 495791 = 495940
  • 167 + 495773 = 495940
  • 191 + 495749 = 495940

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 495,940 and was likely granted around 1893.

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