Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542840, here are decompositions:

13 + 33542827 = 33542840
61 + 33542779 = 33542840
103 + 33542737 = 33542840
181 + 33542659 = 33542840
223 + 33542617 = 33542840
229 + 33542611 = 33542840
277 + 33542563 = 33542840
283 + 33542557 = 33542840

Showing the first eight; more decompositions exist.
