Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524320, here are decompositions:

19 + 31524301 = 31524320
43 + 31524277 = 31524320
97 + 31524223 = 31524320
127 + 31524193 = 31524320
229 + 31524091 = 31524320
271 + 31524049 = 31524320
277 + 31524043 = 31524320
307 + 31524013 = 31524320

Showing the first eight; more decompositions exist.
