Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542642, here are decompositions:

31 + 33542611 = 33542642
79 + 33542563 = 33542642
103 + 33542539 = 33542642
151 + 33542491 = 33542642
193 + 33542449 = 33542642
241 + 33542401 = 33542642
283 + 33542359 = 33542642
379 + 33542263 = 33542642

Showing the first eight; more decompositions exist.
