Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681624, here are decompositions:

  • 37 + 8681587 = 8681624
  • 151 + 8681473 = 8681624
  • 157 + 8681467 = 8681624
  • 223 + 8681401 = 8681624
  • 283 + 8681341 = 8681624
  • 307 + 8681317 = 8681624
  • 313 + 8681311 = 8681624
  • 337 + 8681287 = 8681624

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 8,681,624 and was likely granted around 2014.

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