Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524716, here are decompositions:

43 + 31524673 = 31524716
73 + 31524643 = 31524716
109 + 31524607 = 31524716
193 + 31524523 = 31524716
199 + 31524517 = 31524716
313 + 31524403 = 31524716
373 + 31524343 = 31524716
439 + 31524277 = 31524716

Showing the first eight; more decompositions exist.
