Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478420, here are decompositions:

29 + 33478391 = 33478420
83 + 33478337 = 33478420
89 + 33478331 = 33478420
113 + 33478307 = 33478420
137 + 33478283 = 33478420
251 + 33478169 = 33478420
257 + 33478163 = 33478420
293 + 33478127 = 33478420

Showing the first eight; more decompositions exist.
