Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524340, here are decompositions:

47 + 31524293 = 31524340
83 + 31524257 = 31524340
173 + 31524167 = 31524340
179 + 31524161 = 31524340
233 + 31524107 = 31524340
293 + 31524047 = 31524340
317 + 31524023 = 31524340
401 + 31523939 = 31524340

Showing the first eight; more decompositions exist.
