Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564524, here are decompositions:

7 + 31564517 = 31564524
23 + 31564501 = 31564524
137 + 31564387 = 31564524
163 + 31564361 = 31564524
191 + 31564333 = 31564524
193 + 31564331 = 31564524
197 + 31564327 = 31564524
263 + 31564261 = 31564524

Showing the first eight; more decompositions exist.
