Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988224, here are decompositions:

5 + 988219 = 988224
7 + 988217 = 988224
11 + 988213 = 988224
67 + 988157 = 988224
113 + 988111 = 988224
131 + 988093 = 988224
157 + 988067 = 988224
163 + 988061 = 988224

Showing the first eight; more decompositions exist.
