Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522224, here are decompositions:

5 + 31522219 = 31522224
17 + 31522207 = 31522224
43 + 31522181 = 31522224
163 + 31522061 = 31522224
211 + 31522013 = 31522224
233 + 31521991 = 31522224
271 + 31521953 = 31522224
337 + 31521887 = 31522224

Showing the first eight; more decompositions exist.
