Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606990, here are decompositions:

31 + 8606959 = 8606990
61 + 8606929 = 8606990
79 + 8606911 = 8606990
97 + 8606893 = 8606990
127 + 8606863 = 8606990
151 + 8606839 = 8606990
163 + 8606827 = 8606990
193 + 8606797 = 8606990

Showing the first eight; more decompositions exist.
