Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522310, here are decompositions:

13 + 31522297 = 31522310
67 + 31522243 = 31522310
103 + 31522207 = 31522310
181 + 31522129 = 31522310
331 + 31521979 = 31522310
571 + 31521739 = 31522310
643 + 31521667 = 31522310
661 + 31521649 = 31522310

Showing the first eight; more decompositions exist.
