Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620398, here are decompositions:

5 + 8620393 = 8620398
29 + 8620369 = 8620398
37 + 8620361 = 8620398
71 + 8620327 = 8620398
109 + 8620289 = 8620398
131 + 8620267 = 8620398
139 + 8620259 = 8620398
167 + 8620231 = 8620398

Showing the first eight; more decompositions exist.
