Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533666, here are decompositions:

5 + 31533661 = 31533666
7 + 31533659 = 31533666
29 + 31533637 = 31533666
53 + 31533613 = 31533666
67 + 31533599 = 31533666
79 + 31533587 = 31533666
103 + 31533563 = 31533666
149 + 31533517 = 31533666

Showing the first eight; more decompositions exist.
