Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630178, here are decompositions:

5 + 8630173 = 8630178
19 + 8630159 = 8630178
59 + 8630119 = 8630178
61 + 8630117 = 8630178
107 + 8630071 = 8630178
149 + 8630029 = 8630178
197 + 8629981 = 8630178
229 + 8629949 = 8630178

Showing the first eight; more decompositions exist.
