Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613120, here are decompositions:

13 + 8613107 = 8613120
29 + 8613091 = 8613120
31 + 8613089 = 8613120
73 + 8613047 = 8613120
79 + 8613041 = 8613120
101 + 8613019 = 8613120
137 + 8612983 = 8613120
151 + 8612969 = 8613120

Showing the first eight; more decompositions exist.
