Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524682, here are decompositions:

5 + 31524677 = 31524682
41 + 31524641 = 31524682
113 + 31524569 = 31524682
149 + 31524533 = 31524682
173 + 31524509 = 31524682
263 + 31524419 = 31524682
389 + 31524293 = 31524682
521 + 31524161 = 31524682

Showing the first eight; more decompositions exist.
