Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8682100, here are decompositions:

  • 3 + 8682097 = 8682100
  • 59 + 8682041 = 8682100
  • 101 + 8681999 = 8682100
  • 131 + 8681969 = 8682100
  • 263 + 8681837 = 8682100
  • 269 + 8681831 = 8682100
  • 311 + 8681789 = 8682100
  • 431 + 8681669 = 8682100

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 8,682,100 and was likely granted around 2014.

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