Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615264, here are decompositions:

3 + 8615261 = 8615264
67 + 8615197 = 8615264
103 + 8615161 = 8615264
127 + 8615137 = 8615264
181 + 8615083 = 8615264
277 + 8614987 = 8615264
313 + 8614951 = 8615264
397 + 8614867 = 8615264

Showing the first eight; more decompositions exist.
