Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521784, here are decompositions:

31 + 33521753 = 33521784
53 + 33521731 = 33521784
71 + 33521713 = 33521784
73 + 33521711 = 33521784
83 + 33521701 = 33521784
137 + 33521647 = 33521784
313 + 33521471 = 33521784
347 + 33521437 = 33521784

Showing the first eight; more decompositions exist.
