Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671408, here are decompositions:

  • 41 + 8671367 = 8671408
  • 47 + 8671361 = 8671408
  • 101 + 8671307 = 8671408
  • 257 + 8671151 = 8671408
  • 281 + 8671127 = 8671408
  • 311 + 8671097 = 8671408
  • 401 + 8671007 = 8671408
  • 419 + 8670989 = 8671408

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 8,671,408 and was likely granted around 2014.

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