Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524244, here are decompositions:

47 + 31524197 = 31524244
83 + 31524161 = 31524244
137 + 31524107 = 31524244
197 + 31524047 = 31524244
233 + 31524011 = 31524244
443 + 31523801 = 31524244
491 + 31523753 = 31524244
593 + 31523651 = 31524244

Showing the first eight; more decompositions exist.
