Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615268, here are decompositions:

7 + 8615261 = 8615268
31 + 8615237 = 8615268
37 + 8615231 = 8615268
71 + 8615197 = 8615268
107 + 8615161 = 8615268
131 + 8615137 = 8615268
251 + 8615017 = 8615268
281 + 8614987 = 8615268

Showing the first eight; more decompositions exist.
