Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662880, here are decompositions:

  • 13 + 8662867 = 8662880
  • 73 + 8662807 = 8662880
  • 97 + 8662783 = 8662880
  • 151 + 8662729 = 8662880
  • 223 + 8662657 = 8662880
  • 283 + 8662597 = 8662880
  • 349 + 8662531 = 8662880
  • 397 + 8662483 = 8662880

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 8,662,880 and was likely granted around 2014.

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