Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522264, here are decompositions:

17 + 31522247 = 31522264
23 + 31522241 = 31522264
83 + 31522181 = 31522264
173 + 31522091 = 31522264
251 + 31522013 = 31522264
311 + 31521953 = 31522264
401 + 31521863 = 31522264
593 + 31521671 = 31522264

Showing the first eight; more decompositions exist.
