Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700320, here are decompositions:

  • 37 + 8700283 = 8700320
  • 67 + 8700253 = 8700320
  • 127 + 8700193 = 8700320
  • 151 + 8700169 = 8700320
  • 199 + 8700121 = 8700320
  • 241 + 8700079 = 8700320
  • 283 + 8700037 = 8700320
  • 313 + 8700007 = 8700320

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 8,700,320 and was likely granted around 2014.

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