Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524472, here are decompositions:

3 + 31524469 = 31524472
53 + 31524419 = 31524472
179 + 31524293 = 31524472
311 + 31524161 = 31524472
449 + 31524023 = 31524472
461 + 31524011 = 31524472
719 + 31523753 = 31524472
821 + 31523651 = 31524472

Showing the first eight; more decompositions exist.
