Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564074, here are decompositions:

23 + 31564051 = 31564074
107 + 31563967 = 31564074
127 + 31563947 = 31564074
131 + 31563943 = 31564074
137 + 31563937 = 31564074
163 + 31563911 = 31564074
167 + 31563907 = 31564074
193 + 31563881 = 31564074

Showing the first eight; more decompositions exist.
