Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715994, here are decompositions:

5 + 8715989 = 8715994
17 + 8715977 = 8715994
47 + 8715947 = 8715994
107 + 8715887 = 8715994
113 + 8715881 = 8715994
233 + 8715761 = 8715994
263 + 8715731 = 8715994
347 + 8715647 = 8715994

Showing the first eight; more decompositions exist.
