Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664866, here are decompositions:

  • 3 + 8664863 = 8664866
  • 19 + 8664847 = 8664866
  • 79 + 8664787 = 8664866
  • 109 + 8664757 = 8664866
  • 127 + 8664739 = 8664866
  • 307 + 8664559 = 8664866
  • 313 + 8664553 = 8664866
  • 337 + 8664529 = 8664866

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 8,664,866 and was likely granted around 2014.

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