Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556618, here are decompositions:

5 + 33556613 = 33556618
47 + 33556571 = 33556618
59 + 33556559 = 33556618
71 + 33556547 = 33556618
89 + 33556529 = 33556618
257 + 33556361 = 33556618
317 + 33556301 = 33556618
461 + 33556157 = 33556618

Showing the first eight; more decompositions exist.
