Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561186, here are decompositions:

5 + 33561181 = 33561186
13 + 33561173 = 33561186
17 + 33561169 = 33561186
47 + 33561139 = 33561186
83 + 33561103 = 33561186
97 + 33561089 = 33561186
107 + 33561079 = 33561186
163 + 33561023 = 33561186

Showing the first eight; more decompositions exist.
