Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617960, here are decompositions:

11 + 8617949 = 8617960
17 + 8617943 = 8617960
83 + 8617877 = 8617960
89 + 8617871 = 8617960
137 + 8617823 = 8617960
173 + 8617787 = 8617960
191 + 8617769 = 8617960
257 + 8617703 = 8617960

Showing the first eight; more decompositions exist.
