Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524752, here are decompositions:

31 + 31524721 = 31524752
79 + 31524673 = 31524752
109 + 31524643 = 31524752
211 + 31524541 = 31524752
229 + 31524523 = 31524752
283 + 31524469 = 31524752
349 + 31524403 = 31524752
409 + 31524343 = 31524752

Showing the first eight; more decompositions exist.
