Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564014, here are decompositions:

5 + 31564009 = 31564014
47 + 31563967 = 31564014
61 + 31563953 = 31564014
67 + 31563947 = 31564014
71 + 31563943 = 31564014
73 + 31563941 = 31564014
103 + 31563911 = 31564014
107 + 31563907 = 31564014

Showing the first eight; more decompositions exist.
