Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542790, here are decompositions:

7 + 33542783 = 33542790
11 + 33542779 = 33542790
13 + 33542777 = 33542790
31 + 33542759 = 33542790
37 + 33542753 = 33542790
41 + 33542749 = 33542790
53 + 33542737 = 33542790
67 + 33542723 = 33542790

Showing the first eight; more decompositions exist.
