Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533202, here are decompositions:

11 + 31533191 = 31533202
53 + 31533149 = 31533202
59 + 31533143 = 31533202
83 + 31533119 = 31533202
101 + 31533101 = 31533202
263 + 31532939 = 31533202
509 + 31532693 = 31533202
563 + 31532639 = 31533202

Showing the first eight; more decompositions exist.
