Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542418, here are decompositions:

11 + 33542407 = 33542418
17 + 33542401 = 33542418
29 + 33542389 = 33542418
59 + 33542359 = 33542418
79 + 33542339 = 33542418
97 + 33542321 = 33542418
131 + 33542287 = 33542418
157 + 33542261 = 33542418

Showing the first eight; more decompositions exist.
