Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931938, here are decompositions:

5 + 931933 = 931938
17 + 931921 = 931938
31 + 931907 = 931938
37 + 931901 = 931938
61 + 931877 = 931938
79 + 931859 = 931938
89 + 931849 = 931938
101 + 931837 = 931938

Showing the first eight; more decompositions exist.
