Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33529878, here are decompositions:

7 + 33529871 = 33529878
17 + 33529861 = 33529878
59 + 33529819 = 33529878
89 + 33529789 = 33529878
131 + 33529747 = 33529878
139 + 33529739 = 33529878
157 + 33529721 = 33529878
167 + 33529711 = 33529878

Showing the first eight; more decompositions exist.
