Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542472, here are decompositions:

23 + 33542449 = 33542472
71 + 33542401 = 33542472
83 + 33542389 = 33542472
109 + 33542363 = 33542472
113 + 33542359 = 33542472
149 + 33542323 = 33542472
151 + 33542321 = 33542472
211 + 33542261 = 33542472

Showing the first eight; more decompositions exist.
