Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33551218, here are decompositions:

5 + 33551213 = 33551218
47 + 33551171 = 33551218
89 + 33551129 = 33551218
131 + 33551087 = 33551218
251 + 33550967 = 33551218
269 + 33550949 = 33551218
347 + 33550871 = 33551218
419 + 33550799 = 33551218

Showing the first eight; more decompositions exist.
