Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610020, here are decompositions:

  • 19 + 8610001 = 8610020
  • 103 + 8609917 = 8610020
  • 109 + 8609911 = 8610020
  • 229 + 8609791 = 8610020
  • 337 + 8609683 = 8610020
  • 373 + 8609647 = 8610020
  • 409 + 8609611 = 8610020
  • 439 + 8609581 = 8610020

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 8,610,020 and was likely granted around 2013.

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