Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931908, here are decompositions:

7 + 931901 = 931908
31 + 931877 = 931908
59 + 931849 = 931908
71 + 931837 = 931908
97 + 931811 = 931908
127 + 931781 = 931908
151 + 931757 = 931908
157 + 931751 = 931908

Showing the first eight; more decompositions exist.
