Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524166, here are decompositions:

5 + 31524161 = 31524166
59 + 31524107 = 31524166
227 + 31523939 = 31524166
587 + 31523579 = 31524166
857 + 31523309 = 31524166
887 + 31523279 = 31524166
929 + 31523237 = 31524166
1163 + 31523003 = 31524166

Showing the first eight; more decompositions exist.
