Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630120, here are decompositions:

3 + 8630117 = 8630120
7 + 8630113 = 8630120
139 + 8629981 = 8630120
157 + 8629963 = 8630120
193 + 8629927 = 8630120
211 + 8629909 = 8630120
229 + 8629891 = 8630120
307 + 8629813 = 8630120

Showing the first eight; more decompositions exist.
