Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488720, here are decompositions:

3 + 33488717 = 33488720
37 + 33488683 = 33488720
73 + 33488647 = 33488720
127 + 33488593 = 33488720
151 + 33488569 = 33488720
163 + 33488557 = 33488720
211 + 33488509 = 33488720
229 + 33488491 = 33488720

Showing the first eight; more decompositions exist.
