Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542442, here are decompositions:

41 + 33542401 = 33542442
53 + 33542389 = 33542442
79 + 33542363 = 33542442
83 + 33542359 = 33542442
103 + 33542339 = 33542442
179 + 33542263 = 33542442
181 + 33542261 = 33542442
191 + 33542251 = 33542442

Showing the first eight; more decompositions exist.
