Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615994, here are decompositions:

5 + 8615989 = 8615994
11 + 8615983 = 8615994
31 + 8615963 = 8615994
53 + 8615941 = 8615994
103 + 8615891 = 8615994
113 + 8615881 = 8615994
223 + 8615771 = 8615994
227 + 8615767 = 8615994

Showing the first eight; more decompositions exist.
