Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552032, here are decompositions:

13 + 31552019 = 31552032
53 + 31551979 = 31552032
73 + 31551959 = 31552032
131 + 31551901 = 31552032
173 + 31551859 = 31552032
179 + 31551853 = 31552032
229 + 31551803 = 31552032
251 + 31551781 = 31552032

Showing the first eight; more decompositions exist.
