Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102646, here are decompositions:

  • 3 + 102643 = 102646
  • 53 + 102593 = 102646
  • 59 + 102587 = 102646
  • 83 + 102563 = 102646
  • 107 + 102539 = 102646
  • 113 + 102533 = 102646
  • 149 + 102497 = 102646
  • 239 + 102407 = 102646

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 102,646 and was likely granted around 1870.

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