Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533948, here are decompositions:

29 + 31533919 = 31533948
37 + 31533911 = 31533948
101 + 31533847 = 31533948
109 + 31533839 = 31533948
157 + 31533791 = 31533948
179 + 31533769 = 31533948
227 + 31533721 = 31533948
241 + 31533707 = 31533948

Showing the first eight; more decompositions exist.
