Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621568, here are decompositions:

17 + 8621551 = 8621568
89 + 8621479 = 8621568
101 + 8621467 = 8621568
139 + 8621429 = 8621568
157 + 8621411 = 8621568
191 + 8621377 = 8621568
229 + 8621339 = 8621568
269 + 8621299 = 8621568

Showing the first eight; more decompositions exist.
