Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564176, here are decompositions:

5 + 31564171 = 31564176
13 + 31564163 = 31564176
19 + 31564157 = 31564176
29 + 31564147 = 31564176
37 + 31564139 = 31564176
43 + 31564133 = 31564176
47 + 31564129 = 31564176
73 + 31564103 = 31564176

Showing the first eight; more decompositions exist.
