Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478240, here are decompositions:

41 + 33478199 = 33478240
71 + 33478169 = 33478240
113 + 33478127 = 33478240
179 + 33478061 = 33478240
227 + 33478013 = 33478240
239 + 33478001 = 33478240
269 + 33477971 = 33478240
311 + 33477929 = 33478240

Showing the first eight; more decompositions exist.
