Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597038, here are decompositions:

7 + 31597031 = 31597038
41 + 31596997 = 31597038
47 + 31596991 = 31597038
61 + 31596977 = 31597038
89 + 31596949 = 31597038
131 + 31596907 = 31597038
139 + 31596899 = 31597038
149 + 31596889 = 31597038

Showing the first eight; more decompositions exist.
