Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524250, here are decompositions:

53 + 31524197 = 31524250
83 + 31524167 = 31524250
89 + 31524161 = 31524250
227 + 31524023 = 31524250
239 + 31524011 = 31524250
311 + 31523939 = 31524250
449 + 31523801 = 31524250
599 + 31523651 = 31524250

Showing the first eight; more decompositions exist.
