Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33778, here are decompositions:

5 + 33773 = 33778
11 + 33767 = 33778
29 + 33749 = 33778
131 + 33647 = 33778
137 + 33641 = 33778
149 + 33629 = 33778
179 + 33599 = 33778
191 + 33587 = 33778

Showing the first eight; more decompositions exist.
