Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33563778, here are decompositions:

7 + 33563771 = 33563778
29 + 33563749 = 33563778
37 + 33563741 = 33563778
41 + 33563737 = 33563778
89 + 33563689 = 33563778
167 + 33563611 = 33563778
197 + 33563581 = 33563778
211 + 33563567 = 33563778

Showing the first eight; more decompositions exist.
