Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530722, here are decompositions:

19 + 31530703 = 31530722
43 + 31530679 = 31530722
61 + 31530661 = 31530722
73 + 31530649 = 31530722
79 + 31530643 = 31530722
151 + 31530571 = 31530722
199 + 31530523 = 31530722
271 + 31530451 = 31530722

Showing the first eight; more decompositions exist.
