Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671898, here are decompositions:

  • 61 + 8671837 = 8671898
  • 229 + 8671669 = 8671898
  • 349 + 8671549 = 8671898
  • 379 + 8671519 = 8671898
  • 397 + 8671501 = 8671898
  • 457 + 8671441 = 8671898
  • 577 + 8671321 = 8671898
  • 607 + 8671291 = 8671898

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 8,671,898 and was likely granted around 2014.

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