Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 565816, here are decompositions:

  • 3 + 565813 = 565816
  • 23 + 565793 = 565816
  • 29 + 565787 = 565816
  • 47 + 565769 = 565816
  • 89 + 565727 = 565816
  • 149 + 565667 = 565816
  • 179 + 565637 = 565816
  • 227 + 565589 = 565816

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 565,816 and was likely granted around 1895.

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