Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672642, here are decompositions:

  • 3 + 8672639 = 8672642
  • 79 + 8672563 = 8672642
  • 103 + 8672539 = 8672642
  • 379 + 8672263 = 8672642
  • 439 + 8672203 = 8672642
  • 541 + 8672101 = 8672642
  • 661 + 8671981 = 8672642
  • 1009 + 8671633 = 8672642

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 8,672,642 and was likely granted around 2014.

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