Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524662, here are decompositions:

19 + 31524643 = 31524662
139 + 31524523 = 31524662
163 + 31524499 = 31524662
193 + 31524469 = 31524662
331 + 31524331 = 31524662
439 + 31524223 = 31524662
571 + 31524091 = 31524662
613 + 31524049 = 31524662

Showing the first eight; more decompositions exist.
