Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533186, here are decompositions:

19 + 31533167 = 31533186
37 + 31533149 = 31533186
43 + 31533143 = 31533186
53 + 31533133 = 31533186
59 + 31533127 = 31533186
67 + 31533119 = 31533186
89 + 31533097 = 31533186
173 + 31533013 = 31533186

Showing the first eight; more decompositions exist.
