Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931906, here are decompositions:

5 + 931901 = 931906
23 + 931883 = 931906
29 + 931877 = 931906
47 + 931859 = 931906
149 + 931757 = 931906
167 + 931739 = 931906
179 + 931727 = 931906
197 + 931709 = 931906

Showing the first eight; more decompositions exist.
