Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609444, here are decompositions:

353 + 31609091 = 31609444
491 + 31608953 = 31609444
557 + 31608887 = 31609444
593 + 31608851 = 31609444
857 + 31608587 = 31609444
947 + 31608497 = 31609444
1103 + 31608341 = 31609444
1181 + 31608263 = 31609444

Showing the first eight; more decompositions exist.
