Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508220, here are decompositions:

7 + 33508213 = 33508220
37 + 33508183 = 33508220
61 + 33508159 = 33508220
73 + 33508147 = 33508220
283 + 33507937 = 33508220
307 + 33507913 = 33508220
313 + 33507907 = 33508220
331 + 33507889 = 33508220

Showing the first eight; more decompositions exist.
