Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564034, here are decompositions:

67 + 31563967 = 31564034
97 + 31563937 = 31564034
127 + 31563907 = 31564034
157 + 31563877 = 31564034
163 + 31563871 = 31564034
241 + 31563793 = 31564034
433 + 31563601 = 31564034
571 + 31563463 = 31564034

Showing the first eight; more decompositions exist.
