Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542490, here are decompositions:

13 + 33542477 = 33542490
41 + 33542449 = 33542490
83 + 33542407 = 33542490
89 + 33542401 = 33542490
101 + 33542389 = 33542490
127 + 33542363 = 33542490
131 + 33542359 = 33542490
151 + 33542339 = 33542490

Showing the first eight; more decompositions exist.
