Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557286, here are decompositions:

29 + 33557257 = 33557286
83 + 33557203 = 33557286
89 + 33557197 = 33557286
167 + 33557119 = 33557286
199 + 33557087 = 33557286
223 + 33557063 = 33557286
229 + 33557057 = 33557286
239 + 33557047 = 33557286

Showing the first eight; more decompositions exist.
