Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524328, here are decompositions:

71 + 31524257 = 31524328
131 + 31524197 = 31524328
167 + 31524161 = 31524328
281 + 31524047 = 31524328
317 + 31524011 = 31524328
389 + 31523939 = 31524328
659 + 31523669 = 31524328
677 + 31523651 = 31524328

Showing the first eight; more decompositions exist.
