Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33605856, here are decompositions:

7 + 33605849 = 33605856
13 + 33605843 = 33605856
17 + 33605839 = 33605856
19 + 33605837 = 33605856
59 + 33605797 = 33605856
107 + 33605749 = 33605856
127 + 33605729 = 33605856
139 + 33605717 = 33605856

Showing the first eight; more decompositions exist.
