Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556668, here are decompositions:

71 + 33556597 = 33556668
97 + 33556571 = 33556668
109 + 33556559 = 33556668
137 + 33556531 = 33556668
139 + 33556529 = 33556668
239 + 33556429 = 33556668
269 + 33556399 = 33556668
307 + 33556361 = 33556668

Showing the first eight; more decompositions exist.
