Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538458, here are decompositions:

11 + 33538447 = 33538458
17 + 33538441 = 33538458
71 + 33538387 = 33538458
131 + 33538327 = 33538458
137 + 33538321 = 33538458
199 + 33538259 = 33538458
211 + 33538247 = 33538458
227 + 33538231 = 33538458

Showing the first eight; more decompositions exist.
