Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33542780, here are decompositions:

3 + 33542777 = 33542780
31 + 33542749 = 33542780
43 + 33542737 = 33542780
127 + 33542653 = 33542780
163 + 33542617 = 33542780
223 + 33542557 = 33542780
241 + 33542539 = 33542780
331 + 33542449 = 33542780

Showing the first eight; more decompositions exist.
