Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524684, here are decompositions:

7 + 31524677 = 31524684
11 + 31524673 = 31524684
41 + 31524643 = 31524684
43 + 31524641 = 31524684
97 + 31524587 = 31524684
151 + 31524533 = 31524684
167 + 31524517 = 31524684
281 + 31524403 = 31524684

Showing the first eight; more decompositions exist.
