Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533796, here are decompositions:

5 + 31533791 = 31533796
23 + 31533773 = 31533796
89 + 31533707 = 31533796
137 + 31533659 = 31533796
197 + 31533599 = 31533796
233 + 31533563 = 31533796
263 + 31533533 = 31533796
347 + 31533449 = 31533796

Showing the first eight; more decompositions exist.
