Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564234, here are decompositions:

5 + 31564229 = 31564234
71 + 31564163 = 31564234
101 + 31564133 = 31564234
131 + 31564103 = 31564234
281 + 31563953 = 31564234
293 + 31563941 = 31564234
353 + 31563881 = 31564234
461 + 31563773 = 31564234

Showing the first eight; more decompositions exist.
