Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521868, here are decompositions:

5 + 33521863 = 33521868
7 + 33521861 = 33521868
41 + 33521827 = 33521868
47 + 33521821 = 33521868
71 + 33521797 = 33521868
109 + 33521759 = 33521868
137 + 33521731 = 33521868
139 + 33521729 = 33521868

Showing the first eight; more decompositions exist.
