Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655078, here are decompositions:

7 + 8655071 = 8655078
31 + 8655047 = 8655078
37 + 8655041 = 8655078
41 + 8655037 = 8655078
67 + 8655011 = 8655078
71 + 8655007 = 8655078
97 + 8654981 = 8655078
137 + 8654941 = 8655078

Showing the first eight; more decompositions exist.
