Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564504, here are decompositions:

3 + 31564501 = 31564504
71 + 31564433 = 31564504
113 + 31564391 = 31564504
173 + 31564331 = 31564504
233 + 31564271 = 31564504
263 + 31564241 = 31564504
347 + 31564157 = 31564504
401 + 31564103 = 31564504

Showing the first eight; more decompositions exist.
