Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522328, here are decompositions:

31 + 31522297 = 31522328
109 + 31522219 = 31522328
199 + 31522129 = 31522328
307 + 31522021 = 31522328
337 + 31521991 = 31522328
349 + 31521979 = 31522328
499 + 31521829 = 31522328
661 + 31521667 = 31522328

Showing the first eight; more decompositions exist.
