Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555918, here are decompositions:

5 + 33555913 = 33555918
17 + 33555901 = 33555918
59 + 33555859 = 33555918
101 + 33555817 = 33555918
167 + 33555751 = 33555918
181 + 33555737 = 33555918
191 + 33555727 = 33555918
239 + 33555679 = 33555918

Showing the first eight; more decompositions exist.
