Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615070, here are decompositions:

7 + 8615063 = 8615070
19 + 8615051 = 8615070
53 + 8615017 = 8615070
83 + 8614987 = 8615070
97 + 8614973 = 8615070
103 + 8614967 = 8615070
131 + 8614939 = 8615070
157 + 8614913 = 8615070

Showing the first eight; more decompositions exist.
