Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33585280, here are decompositions:

17 + 33585263 = 33585280
107 + 33585173 = 33585280
137 + 33585143 = 33585280
149 + 33585131 = 33585280
167 + 33585113 = 33585280
317 + 33584963 = 33585280
347 + 33584933 = 33585280
419 + 33584861 = 33585280

Showing the first eight; more decompositions exist.
