Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542538, here are decompositions:

47 + 33542491 = 33542538
61 + 33542477 = 33542538
89 + 33542449 = 33542538
131 + 33542407 = 33542538
137 + 33542401 = 33542538
149 + 33542389 = 33542538
179 + 33542359 = 33542538
199 + 33542339 = 33542538

Showing the first eight; more decompositions exist.
