Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524540, here are decompositions:

7 + 31524533 = 31524540
17 + 31524523 = 31524540
23 + 31524517 = 31524540
31 + 31524509 = 31524540
41 + 31524499 = 31524540
71 + 31524469 = 31524540
137 + 31524403 = 31524540
197 + 31524343 = 31524540

Showing the first eight; more decompositions exist.
