Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478438, here are decompositions:

5 + 33478433 = 33478438
17 + 33478421 = 33478438
47 + 33478391 = 33478438
101 + 33478337 = 33478438
107 + 33478331 = 33478438
131 + 33478307 = 33478438
239 + 33478199 = 33478438
269 + 33478169 = 33478438

Showing the first eight; more decompositions exist.
