Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538768, here are decompositions:

5 + 33538763 = 33538768
47 + 33538721 = 33538768
59 + 33538709 = 33538768
89 + 33538679 = 33538768
149 + 33538619 = 33538768
167 + 33538601 = 33538768
251 + 33538517 = 33538768
257 + 33538511 = 33538768

Showing the first eight; more decompositions exist.
