Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524234, here are decompositions:

11 + 31524223 = 31524234
37 + 31524197 = 31524234
41 + 31524193 = 31524234
67 + 31524167 = 31524234
73 + 31524161 = 31524234
101 + 31524133 = 31524234
127 + 31524107 = 31524234
191 + 31524043 = 31524234

Showing the first eight; more decompositions exist.
