Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524282, here are decompositions:

5 + 31524277 = 31524282
11 + 31524271 = 31524282
59 + 31524223 = 31524282
89 + 31524193 = 31524282
149 + 31524133 = 31524282
191 + 31524091 = 31524282
233 + 31524049 = 31524282
239 + 31524043 = 31524282

Showing the first eight; more decompositions exist.
