Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524774, here are decompositions:

7 + 31524767 = 31524774
11 + 31524763 = 31524774
53 + 31524721 = 31524774
97 + 31524677 = 31524774
101 + 31524673 = 31524774
131 + 31524643 = 31524774
167 + 31524607 = 31524774
233 + 31524541 = 31524774

Showing the first eight; more decompositions exist.
