Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671688, here are decompositions:

  • 19 + 8671669 = 8671688
  • 139 + 8671549 = 8671688
  • 241 + 8671447 = 8671688
  • 307 + 8671381 = 8671688
  • 349 + 8671339 = 8671688
  • 367 + 8671321 = 8671688
  • 397 + 8671291 = 8671688
  • 439 + 8671249 = 8671688

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 8,671,688 and was likely granted around 2014.

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