Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524336, here are decompositions:

5 + 31524331 = 31524336
43 + 31524293 = 31524336
59 + 31524277 = 31524336
79 + 31524257 = 31524336
113 + 31524223 = 31524336
139 + 31524197 = 31524336
229 + 31524107 = 31524336
293 + 31524043 = 31524336

Showing the first eight; more decompositions exist.
