Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988230, here are decompositions:

11 + 988219 = 988230
13 + 988217 = 988230
17 + 988213 = 988230
31 + 988199 = 988230
73 + 988157 = 988230
83 + 988147 = 988230
101 + 988129 = 988230
137 + 988093 = 988230

Showing the first eight; more decompositions exist.
