Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524882, here are decompositions:

19 + 31524863 = 31524882
43 + 31524839 = 31524882
73 + 31524809 = 31524882
89 + 31524793 = 31524882
239 + 31524643 = 31524882
241 + 31524641 = 31524882
313 + 31524569 = 31524882
349 + 31524533 = 31524882

Showing the first eight; more decompositions exist.
