Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533566, here are decompositions:

3 + 31533563 = 31533566
19 + 31533547 = 31533566
67 + 31533499 = 31533566
157 + 31533409 = 31533566
223 + 31533343 = 31533566
307 + 31533259 = 31533566
433 + 31533133 = 31533566
439 + 31533127 = 31533566

Showing the first eight; more decompositions exist.
