Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615958, here are decompositions:

17 + 8615941 = 8615958
41 + 8615917 = 8615958
67 + 8615891 = 8615958
79 + 8615879 = 8615958
149 + 8615809 = 8615958
167 + 8615791 = 8615958
191 + 8615767 = 8615958
251 + 8615707 = 8615958

Showing the first eight; more decompositions exist.
