Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533348, here are decompositions:

5 + 31533343 = 31533348
79 + 31533269 = 31533348
89 + 31533259 = 31533348
139 + 31533209 = 31533348
157 + 31533191 = 31533348
181 + 31533167 = 31533348
199 + 31533149 = 31533348
229 + 31533119 = 31533348

Showing the first eight; more decompositions exist.
