Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533192, here are decompositions:

43 + 31533149 = 31533192
59 + 31533133 = 31533192
73 + 31533119 = 31533192
101 + 31533091 = 31533192
179 + 31533013 = 31533192
191 + 31533001 = 31533192
193 + 31532999 = 31533192
211 + 31532981 = 31533192

Showing the first eight; more decompositions exist.
