Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168860, here are decompositions:

  • 79 + 168781 = 168860
  • 163 + 168697 = 168860
  • 229 + 168631 = 168860
  • 337 + 168523 = 168860
  • 379 + 168481 = 168860
  • 397 + 168463 = 168860
  • 409 + 168451 = 168860
  • 607 + 168253 = 168860

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 168,860 and was likely granted around 1874.

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