Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524276, here are decompositions:

5 + 31524271 = 31524276
19 + 31524257 = 31524276
53 + 31524223 = 31524276
79 + 31524197 = 31524276
83 + 31524193 = 31524276
109 + 31524167 = 31524276
227 + 31524049 = 31524276
229 + 31524047 = 31524276

Showing the first eight; more decompositions exist.
