Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561804, here are decompositions:

  • 7 + 561797 = 561804
  • 17 + 561787 = 561804
  • 37 + 561767 = 561804
  • 43 + 561761 = 561804
  • 71 + 561733 = 561804
  • 101 + 561703 = 561804
  • 137 + 561667 = 561804
  • 197 + 561607 = 561804

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 561,804 and was likely granted around 1895.

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