Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478738, here are decompositions:

11 + 33478727 = 33478738
17 + 33478721 = 33478738
89 + 33478649 = 33478738
131 + 33478607 = 33478738
269 + 33478469 = 33478738
317 + 33478421 = 33478738
347 + 33478391 = 33478738
401 + 33478337 = 33478738

Showing the first eight; more decompositions exist.
