Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564174, here are decompositions:

3 + 31564171 = 31564174
11 + 31564163 = 31564174
17 + 31564157 = 31564174
41 + 31564133 = 31564174
71 + 31564103 = 31564174
227 + 31563947 = 31564174
233 + 31563941 = 31564174
263 + 31563911 = 31564174

Showing the first eight; more decompositions exist.
