Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561858, here are decompositions:

7 + 33561851 = 33561858
19 + 33561839 = 33561858
41 + 33561817 = 33561858
59 + 33561799 = 33561858
79 + 33561779 = 33561858
89 + 33561769 = 33561858
107 + 33561751 = 33561858
139 + 33561719 = 33561858

Showing the first eight; more decompositions exist.
