Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130656, here are decompositions:

  • 5 + 130651 = 130656
  • 7 + 130649 = 130656
  • 13 + 130643 = 130656
  • 17 + 130639 = 130656
  • 23 + 130633 = 130656
  • 37 + 130619 = 130656
  • 67 + 130589 = 130656
  • 103 + 130553 = 130656

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 130,656 and was likely granted around 1872.

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