Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561850, here are decompositions:

11 + 33561839 = 33561850
71 + 33561779 = 33561850
83 + 33561767 = 33561850
107 + 33561743 = 33561850
131 + 33561719 = 33561850
197 + 33561653 = 33561850
239 + 33561611 = 33561850
251 + 33561599 = 33561850

Showing the first eight; more decompositions exist.
