Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524420, here are decompositions:

17 + 31524403 = 31524420
89 + 31524331 = 31524420
127 + 31524293 = 31524420
149 + 31524271 = 31524420
163 + 31524257 = 31524420
197 + 31524223 = 31524420
223 + 31524197 = 31524420
227 + 31524193 = 31524420

Showing the first eight; more decompositions exist.
