Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561880, here are decompositions:

3 + 33561877 = 33561880
29 + 33561851 = 33561880
41 + 33561839 = 33561880
101 + 33561779 = 33561880
113 + 33561767 = 33561880
137 + 33561743 = 33561880
227 + 33561653 = 33561880
239 + 33561641 = 33561880

Showing the first eight; more decompositions exist.
