Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621502, here are decompositions:

11 + 8621491 = 8621502
23 + 8621479 = 8621502
59 + 8621443 = 8621502
73 + 8621429 = 8621502
89 + 8621413 = 8621502
163 + 8621339 = 8621502
193 + 8621309 = 8621502
293 + 8621209 = 8621502

Showing the first eight; more decompositions exist.
