Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938970, here are decompositions:

7 + 938963 = 938970
17 + 938953 = 938970
23 + 938947 = 938970
31 + 938939 = 938970
89 + 938881 = 938970
101 + 938869 = 938970
113 + 938857 = 938970
127 + 938843 = 938970

Showing the first eight; more decompositions exist.
