Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613078, here are decompositions:

31 + 8613047 = 8613078
37 + 8613041 = 8613078
59 + 8613019 = 8613078
109 + 8612969 = 8613078
137 + 8612941 = 8613078
151 + 8612927 = 8613078
239 + 8612839 = 8613078
241 + 8612837 = 8613078

Showing the first eight; more decompositions exist.
