Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988220, here are decompositions:

3 + 988217 = 988220
7 + 988213 = 988220
73 + 988147 = 988220
109 + 988111 = 988220
127 + 988093 = 988220
151 + 988069 = 988220
199 + 988021 = 988220
223 + 987997 = 988220

Showing the first eight; more decompositions exist.
