Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513810, here are decompositions:

  • 29 + 513781 = 513810
  • 41 + 513769 = 513810
  • 43 + 513767 = 513810
  • 61 + 513749 = 513810
  • 71 + 513739 = 513810
  • 79 + 513731 = 513810
  • 83 + 513727 = 513810
  • 113 + 513697 = 513810

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 513,810 and was likely granted around 1893.

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