Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564534, here are decompositions:

3 + 31564531 = 31564534
17 + 31564517 = 31564534
101 + 31564433 = 31564534
173 + 31564361 = 31564534
263 + 31564271 = 31564534
293 + 31564241 = 31564534
401 + 31564133 = 31564534
431 + 31564103 = 31564534

Showing the first eight; more decompositions exist.
