Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524852, here are decompositions:

13 + 31524839 = 31524852
43 + 31524809 = 31524852
59 + 31524793 = 31524852
61 + 31524791 = 31524852
89 + 31524763 = 31524852
131 + 31524721 = 31524852
179 + 31524673 = 31524852
211 + 31524641 = 31524852

Showing the first eight; more decompositions exist.
