Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561156, here are decompositions:

17 + 33561139 = 33561156
53 + 33561103 = 33561156
67 + 33561089 = 33561156
89 + 33561067 = 33561156
103 + 33561053 = 33561156
137 + 33561019 = 33561156
149 + 33561007 = 33561156
157 + 33560999 = 33561156

Showing the first eight; more decompositions exist.
