Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718398, here are decompositions:

97 + 8718301 = 8718398
127 + 8718271 = 8718398
151 + 8718247 = 8718398
181 + 8718217 = 8718398
307 + 8718091 = 8718398
439 + 8717959 = 8718398
541 + 8717857 = 8718398
607 + 8717791 = 8718398

Showing the first eight; more decompositions exist.
