Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578356, here are decompositions:

3 + 33578353 = 33578356
83 + 33578273 = 33578356
89 + 33578267 = 33578356
137 + 33578219 = 33578356
257 + 33578099 = 33578356
269 + 33578087 = 33578356
353 + 33578003 = 33578356
389 + 33577967 = 33578356

Showing the first eight; more decompositions exist.
