Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524866, here are decompositions:

3 + 31524863 = 31524866
73 + 31524793 = 31524866
103 + 31524763 = 31524866
193 + 31524673 = 31524866
223 + 31524643 = 31524866
349 + 31524517 = 31524866
367 + 31524499 = 31524866
397 + 31524469 = 31524866

Showing the first eight; more decompositions exist.
