Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524574, here are decompositions:

5 + 31524569 = 31524574
41 + 31524533 = 31524574
281 + 31524293 = 31524574
317 + 31524257 = 31524574
467 + 31524107 = 31524574
563 + 31524011 = 31524574
773 + 31523801 = 31524574
821 + 31523753 = 31524574

Showing the first eight; more decompositions exist.
