Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597044, here are decompositions:

13 + 31597031 = 31597044
41 + 31597003 = 31597044
47 + 31596997 = 31597044
53 + 31596991 = 31597044
67 + 31596977 = 31597044
131 + 31596913 = 31597044
137 + 31596907 = 31597044
163 + 31596881 = 31597044

Showing the first eight; more decompositions exist.
