Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522352, here are decompositions:

13 + 31522339 = 31522352
109 + 31522243 = 31522352
223 + 31522129 = 31522352
331 + 31522021 = 31522352
373 + 31521979 = 31522352
523 + 31521829 = 31522352
613 + 31521739 = 31522352
709 + 31521643 = 31522352

Showing the first eight; more decompositions exist.
