Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567056, here are decompositions:

7 + 31567049 = 31567056
13 + 31567043 = 31567056
83 + 31566973 = 31567056
89 + 31566967 = 31567056
137 + 31566919 = 31567056
193 + 31566863 = 31567056
229 + 31566827 = 31567056
239 + 31566817 = 31567056

Showing the first eight; more decompositions exist.
