Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567232, here are decompositions:

13 + 31567219 = 31567232
19 + 31567213 = 31567232
79 + 31567153 = 31567232
313 + 31566919 = 31567232
331 + 31566901 = 31567232
439 + 31566793 = 31567232
523 + 31566709 = 31567232
601 + 31566631 = 31567232

Showing the first eight; more decompositions exist.
