Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552152, here are decompositions:

13 + 31552139 = 31552152
83 + 31552069 = 31552152
103 + 31552049 = 31552152
173 + 31551979 = 31552152
193 + 31551959 = 31552152
211 + 31551941 = 31552152
251 + 31551901 = 31552152
293 + 31551859 = 31552152

Showing the first eight; more decompositions exist.
