Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542178, here are decompositions:

11 + 33542167 = 33542178
31 + 33542147 = 33542178
41 + 33542137 = 33542178
67 + 33542111 = 33542178
101 + 33542077 = 33542178
127 + 33542051 = 33542178
181 + 33541997 = 33542178
191 + 33541987 = 33542178

Showing the first eight; more decompositions exist.
