Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616142, here are decompositions:

11 + 8616131 = 8616142
53 + 8616089 = 8616142
71 + 8616071 = 8616142
113 + 8616029 = 8616142
131 + 8616011 = 8616142
179 + 8615963 = 8616142
251 + 8615891 = 8616142
263 + 8615879 = 8616142

Showing the first eight; more decompositions exist.
