Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524150, here are decompositions:

17 + 31524133 = 31524150
43 + 31524107 = 31524150
59 + 31524091 = 31524150
101 + 31524049 = 31524150
103 + 31524047 = 31524150
107 + 31524043 = 31524150
127 + 31524023 = 31524150
137 + 31524013 = 31524150

Showing the first eight; more decompositions exist.
