Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522028, here are decompositions:

7 + 31522021 = 31522028
37 + 31521991 = 31522028
199 + 31521829 = 31522028
379 + 31521649 = 31522028
457 + 31521571 = 31522028
487 + 31521541 = 31522028
547 + 31521481 = 31522028
619 + 31521409 = 31522028

Showing the first eight; more decompositions exist.
