Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564192, here are decompositions:

29 + 31564163 = 31564192
53 + 31564139 = 31564192
59 + 31564133 = 31564192
89 + 31564103 = 31564192
113 + 31564079 = 31564192
239 + 31563953 = 31564192
251 + 31563941 = 31564192
263 + 31563929 = 31564192

Showing the first eight; more decompositions exist.
