Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524756, here are decompositions:

79 + 31524677 = 31524756
83 + 31524673 = 31524756
113 + 31524643 = 31524756
149 + 31524607 = 31524756
223 + 31524533 = 31524756
233 + 31524523 = 31524756
239 + 31524517 = 31524756
257 + 31524499 = 31524756

Showing the first eight; more decompositions exist.
