Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561750, here are decompositions:

  • 17 + 561733 = 561750
  • 37 + 561713 = 561750
  • 47 + 561703 = 561750
  • 83 + 561667 = 561750
  • 151 + 561599 = 561750
  • 191 + 561559 = 561750
  • 197 + 561553 = 561750
  • 199 + 561551 = 561750

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 561,750 and was likely granted around 1895.

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