Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542172, here are decompositions:

5 + 33542167 = 33542172
19 + 33542153 = 33542172
61 + 33542111 = 33542172
71 + 33542101 = 33542172
109 + 33542063 = 33542172
149 + 33542023 = 33542172
193 + 33541979 = 33542172
233 + 33541939 = 33542172

Showing the first eight; more decompositions exist.
