Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556728, here are decompositions:

5 + 33556723 = 33556728
17 + 33556711 = 33556728
47 + 33556681 = 33556728
131 + 33556597 = 33556728
157 + 33556571 = 33556728
181 + 33556547 = 33556728
197 + 33556531 = 33556728
199 + 33556529 = 33556728

Showing the first eight; more decompositions exist.
