Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538788, here are decompositions:

5 + 33538783 = 33538788
29 + 33538759 = 33538788
47 + 33538741 = 33538788
67 + 33538721 = 33538788
79 + 33538709 = 33538788
89 + 33538699 = 33538788
109 + 33538679 = 33538788
139 + 33538649 = 33538788

Showing the first eight; more decompositions exist.
