Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33475840, here are decompositions:

17 + 33475823 = 33475840
89 + 33475751 = 33475840
107 + 33475733 = 33475840
131 + 33475709 = 33475840
227 + 33475613 = 33475840
257 + 33475583 = 33475840
269 + 33475571 = 33475840
317 + 33475523 = 33475840

Showing the first eight; more decompositions exist.
