Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681090, here are decompositions:

  • 13 + 8681077 = 8681090
  • 31 + 8681059 = 8681090
  • 43 + 8681047 = 8681090
  • 97 + 8680993 = 8681090
  • 139 + 8680951 = 8681090
  • 151 + 8680939 = 8681090
  • 181 + 8680909 = 8681090
  • 277 + 8680813 = 8681090

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 8,681,090 and was likely granted around 2014.

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