Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616728, here are decompositions:

7 + 8616721 = 8616728
37 + 8616691 = 8616728
67 + 8616661 = 8616728
181 + 8616547 = 8616728
229 + 8616499 = 8616728
271 + 8616457 = 8616728
331 + 8616397 = 8616728
349 + 8616379 = 8616728

Showing the first eight; more decompositions exist.
