Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567436, here are decompositions:

7 + 31567429 = 31567436
67 + 31567369 = 31567436
139 + 31567297 = 31567436
157 + 31567279 = 31567436
223 + 31567213 = 31567436
283 + 31567153 = 31567436
349 + 31567087 = 31567436
457 + 31566979 = 31567436

Showing the first eight; more decompositions exist.
