Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668340, here are decompositions:

  • 61 + 8668279 = 8668340
  • 67 + 8668273 = 8668340
  • 73 + 8668267 = 8668340
  • 139 + 8668201 = 8668340
  • 199 + 8668141 = 8668340
  • 229 + 8668111 = 8668340
  • 277 + 8668063 = 8668340
  • 283 + 8668057 = 8668340

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 8,668,340 and was likely granted around 2014.

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