Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671500, here are decompositions:

  • 29 + 8671471 = 8671500
  • 31 + 8671469 = 8671500
  • 37 + 8671463 = 8671500
  • 43 + 8671457 = 8671500
  • 53 + 8671447 = 8671500
  • 59 + 8671441 = 8671500
  • 73 + 8671427 = 8671500
  • 107 + 8671393 = 8671500

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 8,671,500 and was likely granted around 2014.

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