Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538878, here are decompositions:

5 + 33538873 = 33538878
11 + 33538867 = 33538878
19 + 33538859 = 33538878
137 + 33538741 = 33538878
157 + 33538721 = 33538878
167 + 33538711 = 33538878
179 + 33538699 = 33538878
199 + 33538679 = 33538878

Showing the first eight; more decompositions exist.
