Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533858, here are decompositions:

11 + 31533847 = 31533858
19 + 31533839 = 31533858
29 + 31533829 = 31533858
67 + 31533791 = 31533858
89 + 31533769 = 31533858
137 + 31533721 = 31533858
151 + 31533707 = 31533858
197 + 31533661 = 31533858

Showing the first eight; more decompositions exist.
