Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615948, here are decompositions:

7 + 8615941 = 8615948
31 + 8615917 = 8615948
67 + 8615881 = 8615948
139 + 8615809 = 8615948
157 + 8615791 = 8615948
181 + 8615767 = 8615948
199 + 8615749 = 8615948
241 + 8615707 = 8615948

Showing the first eight; more decompositions exist.
