Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512880, here are decompositions:

  • 31 + 512849 = 512880
  • 37 + 512843 = 512880
  • 59 + 512821 = 512880
  • 61 + 512819 = 512880
  • 83 + 512797 = 512880
  • 101 + 512779 = 512880
  • 113 + 512767 = 512880
  • 139 + 512741 = 512880

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 512,880 and was likely granted around 1893.

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