Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33615216, here are decompositions:

67 + 33615149 = 33615216
97 + 33615119 = 33615216
137 + 33615079 = 33615216
179 + 33615037 = 33615216
197 + 33615019 = 33615216
199 + 33615017 = 33615216
263 + 33614953 = 33615216
277 + 33614939 = 33615216

Showing the first eight; more decompositions exist.
