Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507216, here are decompositions:

5 + 33507211 = 33507216
79 + 33507137 = 33507216
107 + 33507109 = 33507216
109 + 33507107 = 33507216
137 + 33507079 = 33507216
157 + 33507059 = 33507216
179 + 33507037 = 33507216
269 + 33506947 = 33507216

Showing the first eight; more decompositions exist.
