Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691000, here are decompositions:

  • 29 + 8690971 = 8691000
  • 37 + 8690963 = 8691000
  • 41 + 8690959 = 8691000
  • 47 + 8690953 = 8691000
  • 53 + 8690947 = 8691000
  • 79 + 8690921 = 8691000
  • 83 + 8690917 = 8691000
  • 173 + 8690827 = 8691000

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 8,691,000 and was likely granted around 2014.

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