Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621624, here are decompositions:

7 + 8621617 = 8621624
43 + 8621581 = 8621624
73 + 8621551 = 8621624
157 + 8621467 = 8621624
181 + 8621443 = 8621624
211 + 8621413 = 8621624
523 + 8621101 = 8621624
541 + 8621083 = 8621624

Showing the first eight; more decompositions exist.
