Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629320, here are decompositions:

23 + 8629297 = 8629320
41 + 8629279 = 8629320
79 + 8629241 = 8629320
107 + 8629213 = 8629320
127 + 8629193 = 8629320
149 + 8629171 = 8629320
151 + 8629169 = 8629320
163 + 8629157 = 8629320

Showing the first eight; more decompositions exist.
