Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681278, here are decompositions:

  • 71 + 8681207 = 8681278
  • 101 + 8681177 = 8681278
  • 149 + 8681129 = 8681278
  • 167 + 8681111 = 8681278
  • 257 + 8681021 = 8681278
  • 269 + 8681009 = 8681278
  • 467 + 8680811 = 8681278
  • 509 + 8680769 = 8681278

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 8.681.278 and was likely granted around 2014.

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