Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521838, here are decompositions:

11 + 33521827 = 33521838
17 + 33521821 = 33521838
41 + 33521797 = 33521838
79 + 33521759 = 33521838
107 + 33521731 = 33521838
109 + 33521729 = 33521838
127 + 33521711 = 33521838
137 + 33521701 = 33521838

Showing the first eight; more decompositions exist.
