Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538790, here are decompositions:

3 + 33538787 = 33538790
7 + 33538783 = 33538790
31 + 33538759 = 33538790
79 + 33538711 = 33538790
127 + 33538663 = 33538790
151 + 33538639 = 33538790
157 + 33538633 = 33538790
163 + 33538627 = 33538790

Showing the first eight; more decompositions exist.
