Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524214, here are decompositions:

17 + 31524197 = 31524214
47 + 31524167 = 31524214
53 + 31524161 = 31524214
107 + 31524107 = 31524214
167 + 31524047 = 31524214
191 + 31524023 = 31524214
461 + 31523753 = 31524214
563 + 31523651 = 31524214

Showing the first eight; more decompositions exist.
