Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522448, here are decompositions:

7 + 31522441 = 31522448
37 + 31522411 = 31522448
109 + 31522339 = 31522448
151 + 31522297 = 31522448
229 + 31522219 = 31522448
241 + 31522207 = 31522448
457 + 31521991 = 31522448
619 + 31521829 = 31522448

Showing the first eight; more decompositions exist.
