Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529748, here are decompositions:

31 + 31529717 = 31529748
67 + 31529681 = 31529748
71 + 31529677 = 31529748
79 + 31529669 = 31529748
97 + 31529651 = 31529748
181 + 31529567 = 31529748
191 + 31529557 = 31529748
197 + 31529551 = 31529748

Showing the first eight; more decompositions exist.
