Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561786, here are decompositions:

7 + 33561779 = 33561786
17 + 33561769 = 33561786
19 + 33561767 = 33561786
43 + 33561743 = 33561786
67 + 33561719 = 33561786
107 + 33561679 = 33561786
113 + 33561673 = 33561786
179 + 33561607 = 33561786

Showing the first eight; more decompositions exist.
