Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520656, here are decompositions:

  • 7 + 520649 = 520656
  • 23 + 520633 = 520656
  • 47 + 520609 = 520656
  • 67 + 520589 = 520656
  • 89 + 520567 = 520656
  • 107 + 520549 = 520656
  • 109 + 520547 = 520656
  • 127 + 520529 = 520656

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 520,656 and was likely granted around 1894.

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