Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678166, here are decompositions:

  • 5 + 8678161 = 8678166
  • 17 + 8678149 = 8678166
  • 19 + 8678147 = 8678166
  • 37 + 8678129 = 8678166
  • 53 + 8678113 = 8678166
  • 73 + 8678093 = 8678166
  • 83 + 8678083 = 8678166
  • 97 + 8678069 = 8678166

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 8,678,166 and was likely granted around 2014.

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