Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522238, here are decompositions:

19 + 31522219 = 31522238
31 + 31522207 = 31522238
109 + 31522129 = 31522238
409 + 31521829 = 31522238
499 + 31521739 = 31522238
571 + 31521667 = 31522238
739 + 31521499 = 31522238
757 + 31521481 = 31522238

Showing the first eight; more decompositions exist.
