Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567068, here are decompositions:

19 + 31567049 = 31567068
89 + 31566979 = 31567068
101 + 31566967 = 31567068
149 + 31566919 = 31567068
157 + 31566911 = 31567068
167 + 31566901 = 31567068
229 + 31566839 = 31567068
241 + 31566827 = 31567068

Showing the first eight; more decompositions exist.
