Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542390, here are decompositions:

31 + 33542359 = 33542390
67 + 33542323 = 33542390
103 + 33542287 = 33542390
127 + 33542263 = 33542390
139 + 33542251 = 33542390
157 + 33542233 = 33542390
163 + 33542227 = 33542390
199 + 33542191 = 33542390

Showing the first eight; more decompositions exist.
