Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33555156, here are decompositions:

7 + 33555149 = 33555156
67 + 33555089 = 33555156
79 + 33555077 = 33555156
83 + 33555073 = 33555156
137 + 33555019 = 33555156
163 + 33554993 = 33555156
179 + 33554977 = 33555156
197 + 33554959 = 33555156

Showing the first eight; more decompositions exist.
