Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524714, here are decompositions:

37 + 31524677 = 31524714
41 + 31524673 = 31524714
71 + 31524643 = 31524714
73 + 31524641 = 31524714
107 + 31524607 = 31524714
127 + 31524587 = 31524714
173 + 31524541 = 31524714
181 + 31524533 = 31524714

Showing the first eight; more decompositions exist.
