Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661150, here are decompositions:

13 + 8661137 = 8661150
31 + 8661119 = 8661150
61 + 8661089 = 8661150
89 + 8661061 = 8661150
101 + 8661049 = 8661150
103 + 8661047 = 8661150
107 + 8661043 = 8661150
149 + 8661001 = 8661150

Showing the first eight; more decompositions exist.
