Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542868, here are decompositions:

17 + 33542851 = 33542868
41 + 33542827 = 33542868
67 + 33542801 = 33542868
89 + 33542779 = 33542868
109 + 33542759 = 33542868
131 + 33542737 = 33542868
157 + 33542711 = 33542868
251 + 33542617 = 33542868

Showing the first eight; more decompositions exist.
