Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522244, here are decompositions:

3 + 31522241 = 31522244
37 + 31522207 = 31522244
223 + 31522021 = 31522244
571 + 31521673 = 31522244
577 + 31521667 = 31522244
601 + 31521643 = 31522244
673 + 31521571 = 31522244
811 + 31521433 = 31522244

Showing the first eight; more decompositions exist.
