Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120690, here are decompositions:

  • 13 + 120677 = 120690
  • 19 + 120671 = 120690
  • 29 + 120661 = 120690
  • 43 + 120647 = 120690
  • 67 + 120623 = 120690
  • 71 + 120619 = 120690
  • 83 + 120607 = 120690
  • 103 + 120587 = 120690

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 120,690 and was likely granted around 1871.

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