Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533646, here are decompositions:

5 + 31533641 = 31533646
47 + 31533599 = 31533646
59 + 31533587 = 31533646
83 + 31533563 = 31533646
113 + 31533533 = 31533646
149 + 31533497 = 31533646
197 + 31533449 = 31533646
233 + 31533413 = 31533646

Showing the first eight; more decompositions exist.
