Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552068, here are decompositions:

11 + 31552057 = 31552068
19 + 31552049 = 31552068
71 + 31551997 = 31552068
89 + 31551979 = 31552068
109 + 31551959 = 31552068
127 + 31551941 = 31552068
131 + 31551937 = 31552068
167 + 31551901 = 31552068

Showing the first eight; more decompositions exist.
