Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561612, here are decompositions:

  • 5 + 561607 = 561612
  • 13 + 561599 = 561612
  • 53 + 561559 = 561612
  • 59 + 561553 = 561612
  • 61 + 561551 = 561612
  • 83 + 561529 = 561612
  • 151 + 561461 = 561612
  • 173 + 561439 = 561612

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 561,612 and was likely granted around 1895.

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