Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931930, here are decompositions:

17 + 931913 = 931930
23 + 931907 = 931930
29 + 931901 = 931930
47 + 931883 = 931930
53 + 931877 = 931930
71 + 931859 = 931930
149 + 931781 = 931930
173 + 931757 = 931930

Showing the first eight; more decompositions exist.
