Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524884, here are decompositions:

163 + 31524721 = 31524884
211 + 31524673 = 31524884
241 + 31524643 = 31524884
277 + 31524607 = 31524884
367 + 31524517 = 31524884
541 + 31524343 = 31524884
607 + 31524277 = 31524884
613 + 31524271 = 31524884

Showing the first eight; more decompositions exist.
