Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616400, here are decompositions:

3 + 8616397 = 8616400
29 + 8616371 = 8616400
47 + 8616353 = 8616400
101 + 8616299 = 8616400
179 + 8616221 = 8616400
197 + 8616203 = 8616400
227 + 8616173 = 8616400
251 + 8616149 = 8616400

Showing the first eight; more decompositions exist.
