Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524198, here are decompositions:

5 + 31524193 = 31524198
31 + 31524167 = 31524198
37 + 31524161 = 31524198
107 + 31524091 = 31524198
149 + 31524049 = 31524198
151 + 31524047 = 31524198
257 + 31523941 = 31524198
281 + 31523917 = 31524198

Showing the first eight; more decompositions exist.
