Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33563840, here are decompositions:

3 + 33563837 = 33563840
7 + 33563833 = 33563840
19 + 33563821 = 33563840
31 + 33563809 = 33563840
103 + 33563737 = 33563840
151 + 33563689 = 33563840
229 + 33563611 = 33563840
307 + 33563533 = 33563840

Showing the first eight; more decompositions exist.
