Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667776, here are decompositions:

  • 43 + 8667733 = 8667776
  • 79 + 8667697 = 8667776
  • 163 + 8667613 = 8667776
  • 349 + 8667427 = 8667776
  • 373 + 8667403 = 8667776
  • 457 + 8667319 = 8667776
  • 463 + 8667313 = 8667776
  • 487 + 8667289 = 8667776

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 8,667,776 and was likely granted around 2014.

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