Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567038, here are decompositions:

59 + 31566979 = 31567038
71 + 31566967 = 31567038
127 + 31566911 = 31567038
137 + 31566901 = 31567038
199 + 31566839 = 31567038
211 + 31566827 = 31567038
241 + 31566797 = 31567038
379 + 31566659 = 31567038

Showing the first eight; more decompositions exist.
