Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521730, here are decompositions:

17 + 33521713 = 33521730
19 + 33521711 = 33521730
29 + 33521701 = 33521730
37 + 33521693 = 33521730
41 + 33521689 = 33521730
83 + 33521647 = 33521730
101 + 33521629 = 33521730
107 + 33521623 = 33521730

Showing the first eight; more decompositions exist.
