Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564194, here are decompositions:

23 + 31564171 = 31564194
31 + 31564163 = 31564194
37 + 31564157 = 31564194
47 + 31564147 = 31564194
61 + 31564133 = 31564194
227 + 31563967 = 31564194
241 + 31563953 = 31564194
251 + 31563943 = 31564194

Showing the first eight; more decompositions exist.
