Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668190, here are decompositions:

  • 79 + 8668111 = 8668190
  • 109 + 8668081 = 8668190
  • 127 + 8668063 = 8668190
  • 211 + 8667979 = 8668190
  • 229 + 8667961 = 8668190
  • 241 + 8667949 = 8668190
  • 277 + 8667913 = 8668190
  • 283 + 8667907 = 8668190

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 8 668 190 and was likely granted around 2014.

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