Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524066, here are decompositions:

17 + 31524049 = 31524066
19 + 31524047 = 31524066
23 + 31524043 = 31524066
43 + 31524023 = 31524066
53 + 31524013 = 31524066
113 + 31523953 = 31524066
127 + 31523939 = 31524066
149 + 31523917 = 31524066

Showing the first eight; more decompositions exist.
