Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533042, here are decompositions:

29 + 31533013 = 31533042
41 + 31533001 = 31533042
43 + 31532999 = 31533042
61 + 31532981 = 31533042
71 + 31532971 = 31533042
83 + 31532959 = 31533042
103 + 31532939 = 31533042
179 + 31532863 = 31533042

Showing the first eight; more decompositions exist.
