Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33627220, here are decompositions:

17 + 33627203 = 33627220
41 + 33627179 = 33627220
71 + 33627149 = 33627220
131 + 33627089 = 33627220
191 + 33627029 = 33627220
227 + 33626993 = 33627220
233 + 33626987 = 33627220
239 + 33626981 = 33627220

Showing the first eight; more decompositions exist.
