Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524412, here are decompositions:

251 + 31524161 = 31524412
389 + 31524023 = 31524412
401 + 31524011 = 31524412
659 + 31523753 = 31524412
743 + 31523669 = 31524412
761 + 31523651 = 31524412
971 + 31523441 = 31524412
1013 + 31523399 = 31524412

Showing the first eight; more decompositions exist.
