Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524252, here are decompositions:

29 + 31524223 = 31524252
59 + 31524193 = 31524252
229 + 31524023 = 31524252
239 + 31524013 = 31524252
241 + 31524011 = 31524252
311 + 31523941 = 31524252
313 + 31523939 = 31524252
401 + 31523851 = 31524252

Showing the first eight; more decompositions exist.
