Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33627178, here are decompositions:

29 + 33627149 = 33627178
89 + 33627089 = 33627178
149 + 33627029 = 33627178
191 + 33626987 = 33627178
197 + 33626981 = 33627178
227 + 33626951 = 33627178
317 + 33626861 = 33627178
359 + 33626819 = 33627178

Showing the first eight; more decompositions exist.
