Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521820, here are decompositions:

23 + 33521797 = 33521820
37 + 33521783 = 33521820
61 + 33521759 = 33521820
67 + 33521753 = 33521820
89 + 33521731 = 33521820
107 + 33521713 = 33521820
109 + 33521711 = 33521820
127 + 33521693 = 33521820

Showing the first eight; more decompositions exist.
