Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524552, here are decompositions:

11 + 31524541 = 31524552
19 + 31524533 = 31524552
29 + 31524523 = 31524552
43 + 31524509 = 31524552
53 + 31524499 = 31524552
83 + 31524469 = 31524552
149 + 31524403 = 31524552
251 + 31524301 = 31524552

Showing the first eight; more decompositions exist.
