Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488028, here are decompositions:

29 + 33487999 = 33488028
59 + 33487969 = 33488028
127 + 33487901 = 33488028
151 + 33487877 = 33488028
181 + 33487847 = 33488028
257 + 33487771 = 33488028
269 + 33487759 = 33488028
271 + 33487757 = 33488028

Showing the first eight; more decompositions exist.
