Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630130, here are decompositions:

11 + 8630119 = 8630130
13 + 8630117 = 8630130
17 + 8630113 = 8630130
59 + 8630071 = 8630130
101 + 8630029 = 8630130
127 + 8630003 = 8630130
149 + 8629981 = 8630130
167 + 8629963 = 8630130

Showing the first eight; more decompositions exist.
