Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478212, here are decompositions:

11 + 33478201 = 33478212
13 + 33478199 = 33478212
23 + 33478189 = 33478212
29 + 33478183 = 33478212
43 + 33478169 = 33478212
59 + 33478153 = 33478212
101 + 33478111 = 33478212
149 + 33478063 = 33478212

Showing the first eight; more decompositions exist.
