Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681626, here are decompositions:

  • 3 + 8681623 = 8681626
  • 47 + 8681579 = 8681626
  • 59 + 8681567 = 8681626
  • 113 + 8681513 = 8681626
  • 137 + 8681489 = 8681626
  • 179 + 8681447 = 8681626
  • 197 + 8681429 = 8681626
  • 257 + 8681369 = 8681626

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 8,681,626 and was likely granted around 2014.

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