Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542220, here are decompositions:

29 + 33542191 = 33542220
31 + 33542189 = 33542220
53 + 33542167 = 33542220
67 + 33542153 = 33542220
73 + 33542147 = 33542220
83 + 33542137 = 33542220
109 + 33542111 = 33542220
157 + 33542063 = 33542220

Showing the first eight; more decompositions exist.
