Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533154, here are decompositions:

5 + 31533149 = 31533154
11 + 31533143 = 31533154
53 + 31533101 = 31533154
173 + 31532981 = 31533154
281 + 31532873 = 31533154
461 + 31532693 = 31533154
467 + 31532687 = 31533154
557 + 31532597 = 31533154

Showing the first eight; more decompositions exist.
