Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33543390, here are decompositions:

17 + 33543373 = 33543390
31 + 33543359 = 33543390
53 + 33543337 = 33543390
59 + 33543331 = 33543390
103 + 33543287 = 33543390
137 + 33543253 = 33543390
151 + 33543239 = 33543390
191 + 33543199 = 33543390

Showing the first eight; more decompositions exist.
