Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109642, here are decompositions:

  • 3 + 109639 = 109642
  • 23 + 109619 = 109642
  • 53 + 109589 = 109642
  • 59 + 109583 = 109642
  • 101 + 109541 = 109642
  • 173 + 109469 = 109642
  • 191 + 109451 = 109642
  • 251 + 109391 = 109642

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 109,642 and was likely granted around 1871.

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