Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564334, here are decompositions:

3 + 31564331 = 31564334
7 + 31564327 = 31564334
13 + 31564321 = 31564334
73 + 31564261 = 31564334
97 + 31564237 = 31564334
127 + 31564207 = 31564334
163 + 31564171 = 31564334
283 + 31564051 = 31564334

Showing the first eight; more decompositions exist.
