Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616512, here are decompositions:

13 + 8616499 = 8616512
19 + 8616493 = 8616512
139 + 8616373 = 8616512
193 + 8616319 = 8616512
241 + 8616271 = 8616512
271 + 8616241 = 8616512
313 + 8616199 = 8616512
523 + 8615989 = 8616512

Showing the first eight; more decompositions exist.
