Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664186, here are decompositions:

  • 5 + 8664181 = 8664186
  • 29 + 8664157 = 8664186
  • 79 + 8664107 = 8664186
  • 149 + 8664037 = 8664186
  • 163 + 8664023 = 8664186
  • 199 + 8663987 = 8664186
  • 227 + 8663959 = 8664186
  • 263 + 8663923 = 8664186

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 8,664,186 and was likely granted around 2014.

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