Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524666, here are decompositions:

23 + 31524643 = 31524666
59 + 31524607 = 31524666
79 + 31524587 = 31524666
97 + 31524569 = 31524666
149 + 31524517 = 31524666
157 + 31524509 = 31524666
167 + 31524499 = 31524666
197 + 31524469 = 31524666

Showing the first eight; more decompositions exist.
