Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533150, here are decompositions:

7 + 31533143 = 31533150
17 + 31533133 = 31533150
23 + 31533127 = 31533150
31 + 31533119 = 31533150
53 + 31533097 = 31533150
59 + 31533091 = 31533150
137 + 31533013 = 31533150
149 + 31533001 = 31533150

Showing the first eight; more decompositions exist.
