Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542154, here are decompositions:

7 + 33542147 = 33542154
17 + 33542137 = 33542154
43 + 33542111 = 33542154
53 + 33542101 = 33542154
103 + 33542051 = 33542154
131 + 33542023 = 33542154
157 + 33541997 = 33542154
167 + 33541987 = 33542154

Showing the first eight; more decompositions exist.
