Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100646, here are decompositions:

  • 37 + 100609 = 100646
  • 97 + 100549 = 100646
  • 109 + 100537 = 100646
  • 127 + 100519 = 100646
  • 163 + 100483 = 100646
  • 199 + 100447 = 100646
  • 229 + 100417 = 100646
  • 283 + 100363 = 100646

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 100,646 and was likely granted around 1870.

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