Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630172, here are decompositions:

13 + 8630159 = 8630172
53 + 8630119 = 8630172
59 + 8630113 = 8630172
101 + 8630071 = 8630172
191 + 8629981 = 8630172
211 + 8629961 = 8630172
223 + 8629949 = 8630172
263 + 8629909 = 8630172

Showing the first eight; more decompositions exist.
