Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533074, here are decompositions:

61 + 31533013 = 31533074
73 + 31533001 = 31533074
103 + 31532971 = 31533074
151 + 31532923 = 31533074
193 + 31532881 = 31533074
211 + 31532863 = 31533074
241 + 31532833 = 31533074
337 + 31532737 = 31533074

Showing the first eight; more decompositions exist.
