Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616278, here are decompositions:

7 + 8616271 = 8616278
31 + 8616247 = 8616278
37 + 8616241 = 8616278
61 + 8616217 = 8616278
79 + 8616199 = 8616278
109 + 8616169 = 8616278
127 + 8616151 = 8616278
241 + 8616037 = 8616278

Showing the first eight; more decompositions exist.
