Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522208, here are decompositions:

79 + 31522129 = 31522208
229 + 31521979 = 31522208
379 + 31521829 = 31522208
541 + 31521667 = 31522208
709 + 31521499 = 31522208
727 + 31521481 = 31522208
769 + 31521439 = 31522208
937 + 31521271 = 31522208

Showing the first eight; more decompositions exist.
