Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623398, here are decompositions:

5 + 8623393 = 8623398
41 + 8623357 = 8623398
59 + 8623339 = 8623398
79 + 8623319 = 8623398
107 + 8623291 = 8623398
137 + 8623261 = 8623398
149 + 8623249 = 8623398
151 + 8623247 = 8623398

Showing the first eight; more decompositions exist.
