Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569324, here are decompositions:

5 + 31569319 = 31569324
23 + 31569301 = 31569324
37 + 31569287 = 31569324
43 + 31569281 = 31569324
47 + 31569277 = 31569324
67 + 31569257 = 31569324
131 + 31569193 = 31569324
167 + 31569157 = 31569324

Showing the first eight; more decompositions exist.
