Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542786, here are decompositions:

3 + 33542783 = 33542786
7 + 33542779 = 33542786
37 + 33542749 = 33542786
127 + 33542659 = 33542786
223 + 33542563 = 33542786
229 + 33542557 = 33542786
337 + 33542449 = 33542786
379 + 33542407 = 33542786

Showing the first eight; more decompositions exist.
