Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621562, here are decompositions:

11 + 8621551 = 8621562
71 + 8621491 = 8621562
83 + 8621479 = 8621562
109 + 8621453 = 8621562
149 + 8621413 = 8621562
151 + 8621411 = 8621562
223 + 8621339 = 8621562
263 + 8621299 = 8621562

Showing the first eight; more decompositions exist.
