Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522236, here are decompositions:

7 + 31522229 = 31522236
17 + 31522219 = 31522236
29 + 31522207 = 31522236
107 + 31522129 = 31522236
223 + 31522013 = 31522236
257 + 31521979 = 31522236
283 + 31521953 = 31522236
349 + 31521887 = 31522236

Showing the first eight; more decompositions exist.
