Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564482, here are decompositions:

23 + 31564459 = 31564482
43 + 31564439 = 31564482
149 + 31564333 = 31564482
151 + 31564331 = 31564482
211 + 31564271 = 31564482
233 + 31564249 = 31564482
239 + 31564243 = 31564482
241 + 31564241 = 31564482

Showing the first eight; more decompositions exist.
