Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33511400, here are decompositions:

3 + 33511397 = 33511400
61 + 33511339 = 33511400
79 + 33511321 = 33511400
103 + 33511297 = 33511400
151 + 33511249 = 33511400
163 + 33511237 = 33511400
229 + 33511171 = 33511400
271 + 33511129 = 33511400

Showing the first eight; more decompositions exist.
