Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564132, here are decompositions:

3 + 31564129 = 31564132
29 + 31564103 = 31564132
53 + 31564079 = 31564132
179 + 31563953 = 31564132
191 + 31563941 = 31564132
233 + 31563899 = 31564132
251 + 31563881 = 31564132
269 + 31563863 = 31564132

Showing the first eight; more decompositions exist.
