Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522270, here are decompositions:

23 + 31522247 = 31522270
29 + 31522241 = 31522270
41 + 31522229 = 31522270
89 + 31522181 = 31522270
167 + 31522103 = 31522270
179 + 31522091 = 31522270
251 + 31522019 = 31522270
257 + 31522013 = 31522270

Showing the first eight; more decompositions exist.
