Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680842, here are decompositions:

  • 19 + 8680823 = 8680842
  • 29 + 8680813 = 8680842
  • 31 + 8680811 = 8680842
  • 41 + 8680801 = 8680842
  • 61 + 8680781 = 8680842
  • 73 + 8680769 = 8680842
  • 89 + 8680753 = 8680842
  • 101 + 8680741 = 8680842

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 8,680,842 and was likely granted around 2014.

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