Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521742, here are decompositions:

11 + 33521731 = 33521742
13 + 33521729 = 33521742
29 + 33521713 = 33521742
31 + 33521711 = 33521742
41 + 33521701 = 33521742
53 + 33521689 = 33521742
113 + 33521629 = 33521742
193 + 33521549 = 33521742

Showing the first eight; more decompositions exist.
