Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671900, here are decompositions:

  • 89 + 8671811 = 8671900
  • 131 + 8671769 = 8671900
  • 179 + 8671721 = 8671900
  • 191 + 8671709 = 8671900
  • 269 + 8671631 = 8671900
  • 311 + 8671589 = 8671900
  • 317 + 8671583 = 8671900
  • 383 + 8671517 = 8671900

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 8,671,900 and was likely granted around 2014.

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