Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687078, here are decompositions:

  • 79 + 8686999 = 8687078
  • 97 + 8686981 = 8687078
  • 271 + 8686807 = 8687078
  • 349 + 8686729 = 8687078
  • 409 + 8686669 = 8687078
  • 577 + 8686501 = 8687078
  • 607 + 8686471 = 8687078
  • 619 + 8686459 = 8687078

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 8,687,078 and was likely granted around 2014.

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