Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524522, here are decompositions:

5 + 31524517 = 31524522
13 + 31524509 = 31524522
23 + 31524499 = 31524522
53 + 31524469 = 31524522
103 + 31524419 = 31524522
179 + 31524343 = 31524522
191 + 31524331 = 31524522
229 + 31524293 = 31524522

Showing the first eight; more decompositions exist.
