Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564012, here are decompositions:

3 + 31564009 = 31564012
23 + 31563989 = 31564012
59 + 31563953 = 31564012
71 + 31563941 = 31564012
83 + 31563929 = 31564012
101 + 31563911 = 31564012
113 + 31563899 = 31564012
131 + 31563881 = 31564012

Showing the first eight; more decompositions exist.
