Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606820, here are decompositions:

23 + 8606797 = 8606820
31 + 8606789 = 8606820
41 + 8606779 = 8606820
83 + 8606737 = 8606820
127 + 8606693 = 8606820
163 + 8606657 = 8606820
199 + 8606621 = 8606820
263 + 8606557 = 8606820

Showing the first eight; more decompositions exist.
