Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533356, here are decompositions:

13 + 31533343 = 31533356
97 + 31533259 = 31533356
223 + 31533133 = 31533356
229 + 31533127 = 31533356
397 + 31532959 = 31533356
433 + 31532923 = 31533356
457 + 31532899 = 31533356
523 + 31532833 = 31533356

Showing the first eight; more decompositions exist.
