Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524706, here are decompositions:

29 + 31524677 = 31524706
137 + 31524569 = 31524706
173 + 31524533 = 31524706
197 + 31524509 = 31524706
449 + 31524257 = 31524706
509 + 31524197 = 31524706
599 + 31524107 = 31524706
659 + 31524047 = 31524706

Showing the first eight; more decompositions exist.
