Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664408, here are decompositions:

  • 19 + 8664389 = 8664408
  • 31 + 8664377 = 8664408
  • 41 + 8664367 = 8664408
  • 79 + 8664329 = 8664408
  • 97 + 8664311 = 8664408
  • 149 + 8664259 = 8664408
  • 227 + 8664181 = 8664408
  • 251 + 8664157 = 8664408

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 8,664,408 and was likely granted around 2014.

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