Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538940, here are decompositions:

3 + 33538937 = 33538940
67 + 33538873 = 33538940
73 + 33538867 = 33538940
139 + 33538801 = 33538940
157 + 33538783 = 33538940
181 + 33538759 = 33538940
199 + 33538741 = 33538940
229 + 33538711 = 33538940

Showing the first eight; more decompositions exist.
