Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 84400, here are decompositions:

11 + 84389 = 84400
23 + 84377 = 84400
53 + 84347 = 84400
83 + 84317 = 84400
101 + 84299 = 84400
137 + 84263 = 84400
179 + 84221 = 84400
257 + 84143 = 84400

Showing the first eight; more decompositions exist.
