Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564110, here are decompositions:

7 + 31564103 = 31564110
31 + 31564079 = 31564110
59 + 31564051 = 31564110
101 + 31564009 = 31564110
131 + 31563979 = 31564110
157 + 31563953 = 31564110
163 + 31563947 = 31564110
167 + 31563943 = 31564110

Showing the first eight; more decompositions exist.
