Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668860, here are decompositions:

  • 23 + 8668837 = 8668860
  • 29 + 8668831 = 8668860
  • 43 + 8668817 = 8668860
  • 47 + 8668813 = 8668860
  • 59 + 8668801 = 8668860
  • 61 + 8668799 = 8668860
  • 97 + 8668763 = 8668860
  • 139 + 8668721 = 8668860

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 8,668,860 and was likely granted around 2014.

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