Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564026, here are decompositions:

17 + 31564009 = 31564026
37 + 31563989 = 31564026
47 + 31563979 = 31564026
59 + 31563967 = 31564026
73 + 31563953 = 31564026
79 + 31563947 = 31564026
83 + 31563943 = 31564026
89 + 31563937 = 31564026

Showing the first eight; more decompositions exist.
