Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581938, here are decompositions:

11 + 33581927 = 33581938
17 + 33581921 = 33581938
101 + 33581837 = 33581938
197 + 33581741 = 33581938
251 + 33581687 = 33581938
317 + 33581621 = 33581938
557 + 33581381 = 33581938
587 + 33581351 = 33581938

Showing the first eight; more decompositions exist.
