Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680140, here are decompositions:

  • 19 + 8680121 = 8680140
  • 37 + 8680103 = 8680140
  • 41 + 8680099 = 8680140
  • 67 + 8680073 = 8680140
  • 97 + 8680043 = 8680140
  • 103 + 8680037 = 8680140
  • 107 + 8680033 = 8680140
  • 113 + 8680027 = 8680140

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 8,680,140 and was likely granted around 2014.

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