Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634400, here are decompositions:

3 + 8634397 = 8634400
17 + 8634383 = 8634400
29 + 8634371 = 8634400
41 + 8634359 = 8634400
53 + 8634347 = 8634400
101 + 8634299 = 8634400
149 + 8634251 = 8634400
167 + 8634233 = 8634400

Showing the first eight; more decompositions exist.
