Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700860, here are decompositions:

  • 43 + 8700817 = 8700860
  • 61 + 8700799 = 8700860
  • 67 + 8700793 = 8700860
  • 109 + 8700751 = 8700860
  • 139 + 8700721 = 8700860
  • 151 + 8700709 = 8700860
  • 163 + 8700697 = 8700860
  • 211 + 8700649 = 8700860

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 8,700,860 and was likely granted around 2014.

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