Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524294, here are decompositions:

17 + 31524277 = 31524294
23 + 31524271 = 31524294
37 + 31524257 = 31524294
71 + 31524223 = 31524294
97 + 31524197 = 31524294
101 + 31524193 = 31524294
127 + 31524167 = 31524294
251 + 31524043 = 31524294

Showing the first eight; more decompositions exist.
