Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533194, here are decompositions:

3 + 31533191 = 31533194
61 + 31533133 = 31533194
67 + 31533127 = 31533194
97 + 31533097 = 31533194
103 + 31533091 = 31533194
181 + 31533013 = 31533194
193 + 31533001 = 31533194
223 + 31532971 = 31533194

Showing the first eight; more decompositions exist.
