Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33539040, here are decompositions:

23 + 33539017 = 33539040
37 + 33539003 = 33539040
53 + 33538987 = 33539040
61 + 33538979 = 33539040
89 + 33538951 = 33539040
103 + 33538937 = 33539040
127 + 33538913 = 33539040
149 + 33538891 = 33539040

Showing the first eight; more decompositions exist.
