Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567226, here are decompositions:

7 + 31567219 = 31567226
13 + 31567213 = 31567226
73 + 31567153 = 31567226
139 + 31567087 = 31567226
307 + 31566919 = 31567226
409 + 31566817 = 31567226
433 + 31566793 = 31567226
463 + 31566763 = 31567226

Showing the first eight; more decompositions exist.
