Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631100, here are decompositions:

  • 3 + 8631097 = 8631100
  • 17 + 8631083 = 8631100
  • 59 + 8631041 = 8631100
  • 83 + 8631017 = 8631100
  • 89 + 8631011 = 8631100
  • 197 + 8630903 = 8631100
  • 239 + 8630861 = 8631100
  • 263 + 8630837 = 8631100

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 8,631,100 and was likely granted around 2014.

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