Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478398, here are decompositions:

7 + 33478391 = 33478398
11 + 33478387 = 33478398
61 + 33478337 = 33478398
67 + 33478331 = 33478398
167 + 33478231 = 33478398
197 + 33478201 = 33478398
199 + 33478199 = 33478398
229 + 33478169 = 33478398

Showing the first eight; more decompositions exist.
