Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567196, here are decompositions:

43 + 31567153 = 31567196
109 + 31567087 = 31567196
223 + 31566973 = 31567196
229 + 31566967 = 31567196
277 + 31566919 = 31567196
379 + 31566817 = 31567196
433 + 31566763 = 31567196
487 + 31566709 = 31567196

Showing the first eight; more decompositions exist.
