Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522252, here are decompositions:

5 + 31522247 = 31522252
11 + 31522241 = 31522252
23 + 31522229 = 31522252
71 + 31522181 = 31522252
149 + 31522103 = 31522252
191 + 31522061 = 31522252
233 + 31522019 = 31522252
239 + 31522013 = 31522252

Showing the first eight; more decompositions exist.
