Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524264, here are decompositions:

7 + 31524257 = 31524264
41 + 31524223 = 31524264
67 + 31524197 = 31524264
71 + 31524193 = 31524264
97 + 31524167 = 31524264
103 + 31524161 = 31524264
131 + 31524133 = 31524264
157 + 31524107 = 31524264

Showing the first eight; more decompositions exist.
