Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616788, here are decompositions:

7 + 8616781 = 8616788
31 + 8616757 = 8616788
67 + 8616721 = 8616788
97 + 8616691 = 8616788
109 + 8616679 = 8616788
127 + 8616661 = 8616788
241 + 8616547 = 8616788
331 + 8616457 = 8616788

Showing the first eight; more decompositions exist.
