Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33474978, here are decompositions:

11 + 33474967 = 33474978
29 + 33474949 = 33474978
41 + 33474937 = 33474978
67 + 33474911 = 33474978
107 + 33474871 = 33474978
109 + 33474869 = 33474978
137 + 33474841 = 33474978
149 + 33474829 = 33474978

Showing the first eight; more decompositions exist.
