Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33478278, here are decompositions:

5 + 33478273 = 33478278
47 + 33478231 = 33478278
79 + 33478199 = 33478278
89 + 33478189 = 33478278
101 + 33478177 = 33478278
109 + 33478169 = 33478278
151 + 33478127 = 33478278
157 + 33478121 = 33478278

Showing the first eight; more decompositions exist.
