Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542238, here are decompositions:

5 + 33542233 = 33542238
11 + 33542227 = 33542238
19 + 33542219 = 33542238
47 + 33542191 = 33542238
71 + 33542167 = 33542238
101 + 33542137 = 33542238
127 + 33542111 = 33542238
137 + 33542101 = 33542238

Showing the first eight; more decompositions exist.
