Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524722, here are decompositions:

79 + 31524643 = 31524722
181 + 31524541 = 31524722
199 + 31524523 = 31524722
223 + 31524499 = 31524722
379 + 31524343 = 31524722
421 + 31524301 = 31524722
499 + 31524223 = 31524722
631 + 31524091 = 31524722

Showing the first eight; more decompositions exist.
