Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542144, here are decompositions:

7 + 33542137 = 33542144
43 + 33542101 = 33542144
67 + 33542077 = 33542144
157 + 33541987 = 33542144
211 + 33541933 = 33542144
283 + 33541861 = 33542144
373 + 33541771 = 33542144
421 + 33541723 = 33542144

Showing the first eight; more decompositions exist.
