Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561918, here are decompositions:

7 + 33561911 = 33561918
37 + 33561881 = 33561918
41 + 33561877 = 33561918
67 + 33561851 = 33561918
79 + 33561839 = 33561918
101 + 33561817 = 33561918
139 + 33561779 = 33561918
149 + 33561769 = 33561918

Showing the first eight; more decompositions exist.
