Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552224, here are decompositions:

13 + 31552211 = 31552224
17 + 31552207 = 31552224
31 + 31552193 = 31552224
97 + 31552127 = 31552224
167 + 31552057 = 31552224
191 + 31552033 = 31552224
227 + 31551997 = 31552224
283 + 31551941 = 31552224

Showing the first eight; more decompositions exist.
