Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621630, here are decompositions:

7 + 8621623 = 8621630
13 + 8621617 = 8621630
79 + 8621551 = 8621630
139 + 8621491 = 8621630
151 + 8621479 = 8621630
163 + 8621467 = 8621630
331 + 8621299 = 8621630
349 + 8621281 = 8621630

Showing the first eight; more decompositions exist.
