Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569236, here are decompositions:

3 + 31569233 = 31569236
7 + 31569229 = 31569236
43 + 31569193 = 31569236
67 + 31569169 = 31569236
79 + 31569157 = 31569236
163 + 31569073 = 31569236
199 + 31569037 = 31569236
367 + 31568869 = 31569236

Showing the first eight; more decompositions exist.
