Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524956, here are decompositions:

19 + 31524937 = 31524956
163 + 31524793 = 31524956
193 + 31524763 = 31524956
283 + 31524673 = 31524956
313 + 31524643 = 31524956
349 + 31524607 = 31524956
433 + 31524523 = 31524956
439 + 31524517 = 31524956

Showing the first eight; more decompositions exist.
