Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561912, here are decompositions:

31 + 33561881 = 33561912
61 + 33561851 = 33561912
73 + 33561839 = 33561912
113 + 33561799 = 33561912
193 + 33561719 = 33561912
233 + 33561679 = 33561912
239 + 33561673 = 33561912
271 + 33561641 = 33561912

Showing the first eight; more decompositions exist.
