Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542550, here are decompositions:

11 + 33542539 = 33542550
59 + 33542491 = 33542550
61 + 33542489 = 33542550
73 + 33542477 = 33542550
101 + 33542449 = 33542550
149 + 33542401 = 33542550
191 + 33542359 = 33542550
211 + 33542339 = 33542550

Showing the first eight; more decompositions exist.
