Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706400, here are decompositions:

23 + 8706377 = 8706400
113 + 8706287 = 8706400
149 + 8706251 = 8706400
179 + 8706221 = 8706400
251 + 8706149 = 8706400
293 + 8706107 = 8706400
389 + 8706011 = 8706400
401 + 8705999 = 8706400

Showing the first eight; more decompositions exist.
