Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615960, here are decompositions:

19 + 8615941 = 8615960
43 + 8615917 = 8615960
79 + 8615881 = 8615960
127 + 8615833 = 8615960
151 + 8615809 = 8615960
193 + 8615767 = 8615960
211 + 8615749 = 8615960
307 + 8615653 = 8615960

Showing the first eight; more decompositions exist.
