Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604640, here are decompositions:

  • 17 + 8604623 = 8604640
  • 47 + 8604593 = 8604640
  • 89 + 8604551 = 8604640
  • 101 + 8604539 = 8604640
  • 131 + 8604509 = 8604640
  • 173 + 8604467 = 8604640
  • 227 + 8604413 = 8604640
  • 269 + 8604371 = 8604640

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 8,604,640 and was likely granted around 2013.

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