Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524532, here are decompositions:

23 + 31524509 = 31524532
113 + 31524419 = 31524532
239 + 31524293 = 31524532
509 + 31524023 = 31524532
521 + 31524011 = 31524532
593 + 31523939 = 31524532
863 + 31523669 = 31524532
881 + 31523651 = 31524532

Showing the first eight; more decompositions exist.
