Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567412, here are decompositions:

43 + 31567369 = 31567412
181 + 31567231 = 31567412
193 + 31567219 = 31567412
199 + 31567213 = 31567412
433 + 31566979 = 31567412
439 + 31566973 = 31567412
619 + 31566793 = 31567412
823 + 31566589 = 31567412

Showing the first eight; more decompositions exist.
