Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524516, here are decompositions:

7 + 31524509 = 31524516
17 + 31524499 = 31524516
47 + 31524469 = 31524516
97 + 31524419 = 31524516
113 + 31524403 = 31524516
173 + 31524343 = 31524516
223 + 31524293 = 31524516
239 + 31524277 = 31524516

Showing the first eight; more decompositions exist.
