Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567008, here are decompositions:

29 + 31566979 = 31567008
41 + 31566967 = 31567008
89 + 31566919 = 31567008
97 + 31566911 = 31567008
107 + 31566901 = 31567008
181 + 31566827 = 31567008
191 + 31566817 = 31567008
211 + 31566797 = 31567008

Showing the first eight; more decompositions exist.
