Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90400, here are decompositions:

3 + 90397 = 90400
29 + 90371 = 90400
41 + 90359 = 90400
47 + 90353 = 90400
137 + 90263 = 90400
173 + 90227 = 90400
197 + 90203 = 90400
227 + 90173 = 90400

Showing the first eight; more decompositions exist.
