Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686120, here are decompositions:

  • 17 + 8686103 = 8686120
  • 71 + 8686049 = 8686120
  • 167 + 8685953 = 8686120
  • 197 + 8685923 = 8686120
  • 227 + 8685893 = 8686120
  • 257 + 8685863 = 8686120
  • 263 + 8685857 = 8686120
  • 353 + 8685767 = 8686120

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 8,686,120 and was likely granted around 2014.

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