Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538818, here are decompositions:

17 + 33538801 = 33538818
31 + 33538787 = 33538818
59 + 33538759 = 33538818
97 + 33538721 = 33538818
107 + 33538711 = 33538818
109 + 33538709 = 33538818
139 + 33538679 = 33538818
179 + 33538639 = 33538818

Showing the first eight; more decompositions exist.
