Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615080, here are decompositions:

17 + 8615063 = 8615080
29 + 8615051 = 8615080
101 + 8614979 = 8615080
107 + 8614973 = 8615080
113 + 8614967 = 8615080
167 + 8614913 = 8615080
179 + 8614901 = 8615080
191 + 8614889 = 8615080

Showing the first eight; more decompositions exist.
