Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8675640, here are decompositions:

  • 19 + 8675621 = 8675640
  • 67 + 8675573 = 8675640
  • 131 + 8675509 = 8675640
  • 137 + 8675503 = 8675640
  • 167 + 8675473 = 8675640
  • 191 + 8675449 = 8675640
  • 199 + 8675441 = 8675640
  • 227 + 8675413 = 8675640

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 8,675,640 and was likely granted around 2014.

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