Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524438, here are decompositions:

19 + 31524419 = 31524438
107 + 31524331 = 31524438
137 + 31524301 = 31524438
167 + 31524271 = 31524438
181 + 31524257 = 31524438
241 + 31524197 = 31524438
271 + 31524167 = 31524438
277 + 31524161 = 31524438

Showing the first eight; more decompositions exist.
