Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668238, here are decompositions:

  • 31 + 8668207 = 8668238
  • 37 + 8668201 = 8668238
  • 97 + 8668141 = 8668238
  • 127 + 8668111 = 8668238
  • 157 + 8668081 = 8668238
  • 181 + 8668057 = 8668238
  • 277 + 8667961 = 8668238
  • 307 + 8667931 = 8668238

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 8,668,238 and was likely granted around 2014.

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