Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567296, here are decompositions:

17 + 31567279 = 31567296
29 + 31567267 = 31567296
83 + 31567213 = 31567296
139 + 31567157 = 31567296
317 + 31566979 = 31567296
433 + 31566863 = 31567296
457 + 31566839 = 31567296
479 + 31566817 = 31567296

Showing the first eight; more decompositions exist.
