Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663656, here are decompositions:

  • 3 + 8663653 = 8663656
  • 47 + 8663609 = 8663656
  • 137 + 8663519 = 8663656
  • 149 + 8663507 = 8663656
  • 347 + 8663309 = 8663656
  • 383 + 8663273 = 8663656
  • 503 + 8663153 = 8663656
  • 557 + 8663099 = 8663656

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 8,663,656 and was likely granted around 2014.

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