Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630220, here are decompositions:

13 + 8630207 = 8630220
19 + 8630201 = 8630220
29 + 8630191 = 8630220
41 + 8630179 = 8630220
43 + 8630177 = 8630220
47 + 8630173 = 8630220
61 + 8630159 = 8630220
101 + 8630119 = 8630220

Showing the first eight; more decompositions exist.
