Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667900, here are decompositions:

  • 29 + 8667871 = 8667900
  • 37 + 8667863 = 8667900
  • 53 + 8667847 = 8667900
  • 71 + 8667829 = 8667900
  • 79 + 8667821 = 8667900
  • 103 + 8667797 = 8667900
  • 107 + 8667793 = 8667900
  • 167 + 8667733 = 8667900

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 8,667,900 and was likely granted around 2014.

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