Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938988, here are decompositions:

5 + 938983 = 938988
7 + 938981 = 938988
19 + 938969 = 938988
41 + 938947 = 938988
67 + 938921 = 938988
107 + 938881 = 938988
109 + 938879 = 938988
131 + 938857 = 938988

Showing the first eight; more decompositions exist.
