Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601640, here are decompositions:

  • 11 + 8601629 = 8601640
  • 53 + 8601587 = 8601640
  • 59 + 8601581 = 8601640
  • 71 + 8601569 = 8601640
  • 83 + 8601557 = 8601640
  • 137 + 8601503 = 8601640
  • 149 + 8601491 = 8601640
  • 191 + 8601449 = 8601640

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 8,601,640 and was likely granted around 2013.

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