Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538398, here are decompositions:

11 + 33538387 = 33538398
31 + 33538367 = 33538398
59 + 33538339 = 33538398
71 + 33538327 = 33538398
139 + 33538259 = 33538398
151 + 33538247 = 33538398
167 + 33538231 = 33538398
181 + 33538217 = 33538398

Showing the first eight; more decompositions exist.
