Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542730, here are decompositions:

7 + 33542723 = 33542730
19 + 33542711 = 33542730
71 + 33542659 = 33542730
113 + 33542617 = 33542730
127 + 33542603 = 33542730
157 + 33542573 = 33542730
163 + 33542567 = 33542730
167 + 33542563 = 33542730

Showing the first eight; more decompositions exist.
