Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524576, here are decompositions:

7 + 31524569 = 31524576
43 + 31524533 = 31524576
53 + 31524523 = 31524576
59 + 31524517 = 31524576
67 + 31524509 = 31524576
107 + 31524469 = 31524576
157 + 31524419 = 31524576
173 + 31524403 = 31524576

Showing the first eight; more decompositions exist.
