Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524936, here are decompositions:

43 + 31524893 = 31524936
73 + 31524863 = 31524936
97 + 31524839 = 31524936
127 + 31524809 = 31524936
139 + 31524797 = 31524936
173 + 31524763 = 31524936
263 + 31524673 = 31524936
293 + 31524643 = 31524936

Showing the first eight; more decompositions exist.
