Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664876, here are decompositions:

  • 5 + 8664871 = 8664876
  • 7 + 8664869 = 8664876
  • 13 + 8664863 = 8664876
  • 19 + 8664857 = 8664876
  • 29 + 8664847 = 8664876
  • 89 + 8664787 = 8664876
  • 137 + 8664739 = 8664876
  • 263 + 8664613 = 8664876

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 8,664,876 and was likely granted around 2014.

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