Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524346, here are decompositions:

3 + 31524343 = 31524346
53 + 31524293 = 31524346
89 + 31524257 = 31524346
149 + 31524197 = 31524346
179 + 31524167 = 31524346
239 + 31524107 = 31524346
593 + 31523753 = 31524346
677 + 31523669 = 31524346

Showing the first eight; more decompositions exist.
