Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552212, here are decompositions:

5 + 31552207 = 31552212
19 + 31552193 = 31552212
73 + 31552139 = 31552212
163 + 31552049 = 31552212
179 + 31552033 = 31552212
193 + 31552019 = 31552212
233 + 31551979 = 31552212
271 + 31551941 = 31552212

Showing the first eight; more decompositions exist.
