Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552216, here are decompositions:

5 + 31552211 = 31552216
23 + 31552193 = 31552216
89 + 31552127 = 31552216
167 + 31552049 = 31552216
197 + 31552019 = 31552216
239 + 31551977 = 31552216
257 + 31551959 = 31552216
359 + 31551857 = 31552216

Showing the first eight; more decompositions exist.
