Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521724, here are decompositions:

11 + 33521713 = 33521724
13 + 33521711 = 33521724
23 + 33521701 = 33521724
31 + 33521693 = 33521724
101 + 33521623 = 33521724
193 + 33521531 = 33521724
241 + 33521483 = 33521724
263 + 33521461 = 33521724

Showing the first eight; more decompositions exist.
