Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33620938, here are decompositions:

11 + 33620927 = 33620938
47 + 33620891 = 33620938
149 + 33620789 = 33620938
257 + 33620681 = 33620938
311 + 33620627 = 33620938
317 + 33620621 = 33620938
347 + 33620591 = 33620938
359 + 33620579 = 33620938

Showing the first eight; more decompositions exist.
