Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542160, here are decompositions:

7 + 33542153 = 33542160
13 + 33542147 = 33542160
23 + 33542137 = 33542160
59 + 33542101 = 33542160
83 + 33542077 = 33542160
97 + 33542063 = 33542160
109 + 33542051 = 33542160
137 + 33542023 = 33542160

Showing the first eight; more decompositions exist.
