Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578278, here are decompositions:

5 + 33578273 = 33578278
11 + 33578267 = 33578278
17 + 33578261 = 33578278
59 + 33578219 = 33578278
131 + 33578147 = 33578278
179 + 33578099 = 33578278
191 + 33578087 = 33578278
311 + 33577967 = 33578278

Showing the first eight; more decompositions exist.
