Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567652, here are decompositions:

3 + 31567649 = 31567652
31 + 31567621 = 31567652
139 + 31567513 = 31567652
223 + 31567429 = 31567652
241 + 31567411 = 31567652
283 + 31567369 = 31567652
373 + 31567279 = 31567652
421 + 31567231 = 31567652

Showing the first eight; more decompositions exist.
