Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624398, here are decompositions:

5 + 8624393 = 8624398
71 + 8624327 = 8624398
131 + 8624267 = 8624398
149 + 8624249 = 8624398
197 + 8624201 = 8624398
239 + 8624159 = 8624398
257 + 8624141 = 8624398
269 + 8624129 = 8624398

Showing the first eight; more decompositions exist.
