Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621252, here are decompositions:

43 + 8621209 = 8621252
109 + 8621143 = 8621252
151 + 8621101 = 8621252
163 + 8621089 = 8621252
379 + 8620873 = 8621252
613 + 8620639 = 8621252
631 + 8620621 = 8621252
709 + 8620543 = 8621252

Showing the first eight; more decompositions exist.
