Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681242, here are decompositions:

  • 29 + 8681213 = 8681242
  • 83 + 8681159 = 8681242
  • 113 + 8681129 = 8681242
  • 131 + 8681111 = 8681242
  • 233 + 8681009 = 8681242
  • 239 + 8681003 = 8681242
  • 419 + 8680823 = 8681242
  • 431 + 8680811 = 8681242

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 8 681 242 and was likely granted around 2014.

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