Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524660, here are decompositions:

17 + 31524643 = 31524660
19 + 31524641 = 31524660
53 + 31524607 = 31524660
73 + 31524587 = 31524660
127 + 31524533 = 31524660
137 + 31524523 = 31524660
151 + 31524509 = 31524660
191 + 31524469 = 31524660

Showing the first eight; more decompositions exist.
