Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 561400, here are decompositions:

11 + 561389 = 561400
23 + 561377 = 561400
41 + 561359 = 561400
53 + 561347 = 561400
149 + 561251 = 561400
227 + 561173 = 561400
239 + 561161 = 561400
317 + 561083 = 561400

Showing the first eight; more decompositions exist.
