Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561780, here are decompositions:

11 + 33561769 = 33561780
13 + 33561767 = 33561780
29 + 33561751 = 33561780
37 + 33561743 = 33561780
61 + 33561719 = 33561780
101 + 33561679 = 33561780
107 + 33561673 = 33561780
127 + 33561653 = 33561780

Showing the first eight; more decompositions exist.
