Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608948, here are decompositions:

11 + 31608937 = 31608948
31 + 31608917 = 31608948
37 + 31608911 = 31608948
61 + 31608887 = 31608948
97 + 31608851 = 31608948
127 + 31608821 = 31608948
131 + 31608817 = 31608948
191 + 31608757 = 31608948

Showing the first eight; more decompositions exist.
