Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661962, here are decompositions:

  • 19 + 8661943 = 8661962
  • 61 + 8661901 = 8661962
  • 73 + 8661889 = 8661962
  • 79 + 8661883 = 8661962
  • 163 + 8661799 = 8661962
  • 193 + 8661769 = 8661962
  • 229 + 8661733 = 8661962
  • 409 + 8661553 = 8661962

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 8,661,962 and was likely granted around 2014.

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