Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524220, here are decompositions:

23 + 31524197 = 31524220
53 + 31524167 = 31524220
59 + 31524161 = 31524220
113 + 31524107 = 31524220
173 + 31524047 = 31524220
197 + 31524023 = 31524220
281 + 31523939 = 31524220
419 + 31523801 = 31524220

Showing the first eight; more decompositions exist.
