Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524436, here are decompositions:

17 + 31524419 = 31524436
179 + 31524257 = 31524436
239 + 31524197 = 31524436
269 + 31524167 = 31524436
389 + 31524047 = 31524436
683 + 31523753 = 31524436
857 + 31523579 = 31524436
1193 + 31523243 = 31524436

Showing the first eight; more decompositions exist.
