Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521812, here are decompositions:

29 + 33521783 = 33521812
53 + 33521759 = 33521812
59 + 33521753 = 33521812
83 + 33521729 = 33521812
101 + 33521711 = 33521812
263 + 33521549 = 33521812
281 + 33521531 = 33521812
419 + 33521393 = 33521812

Showing the first eight; more decompositions exist.
