Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600400, here are decompositions:

7 + 8600393 = 8600400
41 + 8600359 = 8600400
59 + 8600341 = 8600400
167 + 8600233 = 8600400
181 + 8600219 = 8600400
229 + 8600171 = 8600400
239 + 8600161 = 8600400
257 + 8600143 = 8600400

Showing the first eight; more decompositions exist.
