Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522246, here are decompositions:

3 + 31522243 = 31522246
5 + 31522241 = 31522246
17 + 31522229 = 31522246
227 + 31522019 = 31522246
233 + 31522013 = 31522246
269 + 31521977 = 31522246
293 + 31521953 = 31522246
359 + 31521887 = 31522246

Showing the first eight; more decompositions exist.
