Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624400, here are decompositions:

7 + 8624393 = 8624400
17 + 8624383 = 8624400
47 + 8624353 = 8624400
73 + 8624327 = 8624400
89 + 8624311 = 8624400
149 + 8624251 = 8624400
151 + 8624249 = 8624400
157 + 8624243 = 8624400

Showing the first eight; more decompositions exist.
