Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524384, here are decompositions:

41 + 31524343 = 31524384
53 + 31524331 = 31524384
83 + 31524301 = 31524384
107 + 31524277 = 31524384
113 + 31524271 = 31524384
127 + 31524257 = 31524384
191 + 31524193 = 31524384
223 + 31524161 = 31524384

Showing the first eight; more decompositions exist.
