Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681170, here are decompositions:

  • 11 + 8681159 = 8681170
  • 41 + 8681129 = 8681170
  • 53 + 8681117 = 8681170
  • 59 + 8681111 = 8681170
  • 149 + 8681021 = 8681170
  • 167 + 8681003 = 8681170
  • 263 + 8680907 = 8681170
  • 269 + 8680901 = 8681170

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 8,681,170 and was likely granted around 2014.

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