Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621608, here are decompositions:

131 + 8621477 = 8621608
179 + 8621429 = 8621608
197 + 8621411 = 8621608
269 + 8621339 = 8621608
419 + 8621189 = 8621608
461 + 8621147 = 8621608
521 + 8621087 = 8621608
557 + 8621051 = 8621608

Showing the first eight; more decompositions exist.
