Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521874, here are decompositions:

11 + 33521863 = 33521874
13 + 33521861 = 33521874
31 + 33521843 = 33521874
47 + 33521827 = 33521874
53 + 33521821 = 33521874
163 + 33521711 = 33521874
173 + 33521701 = 33521874
181 + 33521693 = 33521874

Showing the first eight; more decompositions exist.
