Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513884, here are decompositions:

  • 3 + 513881 = 513884
  • 13 + 513871 = 513884
  • 43 + 513841 = 513884
  • 103 + 513781 = 513884
  • 157 + 513727 = 513884
  • 193 + 513691 = 513884
  • 211 + 513673 = 513884
  • 373 + 513511 = 513884

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 513,884 and was likely granted around 1893.

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