Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630216, here are decompositions:

37 + 8630179 = 8630216
43 + 8630173 = 8630216
97 + 8630119 = 8630216
103 + 8630113 = 8630216
307 + 8629909 = 8630216
349 + 8629867 = 8630216
619 + 8629597 = 8630216
709 + 8629507 = 8630216

Showing the first eight; more decompositions exist.
