Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542720, here are decompositions:

61 + 33542659 = 33542720
67 + 33542653 = 33542720
103 + 33542617 = 33542720
109 + 33542611 = 33542720
157 + 33542563 = 33542720
163 + 33542557 = 33542720
181 + 33542539 = 33542720
229 + 33542491 = 33542720

Showing the first eight; more decompositions exist.
