Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538738, here are decompositions:

17 + 33538721 = 33538738
29 + 33538709 = 33538738
59 + 33538679 = 33538738
89 + 33538649 = 33538738
137 + 33538601 = 33538738
227 + 33538511 = 33538738
239 + 33538499 = 33538738
257 + 33538481 = 33538738

Showing the first eight; more decompositions exist.
