Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522112, here are decompositions:

229 + 31521883 = 31522112
283 + 31521829 = 31522112
373 + 31521739 = 31522112
439 + 31521673 = 31522112
463 + 31521649 = 31522112
541 + 31521571 = 31522112
571 + 31521541 = 31522112
613 + 31521499 = 31522112

Showing the first eight; more decompositions exist.
