Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615970, here are decompositions:

7 + 8615963 = 8615970
29 + 8615941 = 8615970
53 + 8615917 = 8615970
79 + 8615891 = 8615970
89 + 8615881 = 8615970
137 + 8615833 = 8615970
179 + 8615791 = 8615970
199 + 8615771 = 8615970

Showing the first eight; more decompositions exist.
