Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561882, here are decompositions:

5 + 33561877 = 33561882
31 + 33561851 = 33561882
43 + 33561839 = 33561882
83 + 33561799 = 33561882
103 + 33561779 = 33561882
113 + 33561769 = 33561882
131 + 33561751 = 33561882
139 + 33561743 = 33561882

Showing the first eight; more decompositions exist.
