Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671600, here are decompositions:

  • 11 + 8671589 = 8671600
  • 17 + 8671583 = 8671600
  • 83 + 8671517 = 8671600
  • 89 + 8671511 = 8671600
  • 101 + 8671499 = 8671600
  • 131 + 8671469 = 8671600
  • 137 + 8671463 = 8671600
  • 173 + 8671427 = 8671600

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 8,671,600 and was likely granted around 2014.

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