Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524372, here are decompositions:

29 + 31524343 = 31524372
41 + 31524331 = 31524372
71 + 31524301 = 31524372
79 + 31524293 = 31524372
101 + 31524271 = 31524372
149 + 31524223 = 31524372
179 + 31524193 = 31524372
211 + 31524161 = 31524372

Showing the first eight; more decompositions exist.
