Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658960, here are decompositions:

17 + 8658943 = 8658960
19 + 8658941 = 8658960
29 + 8658931 = 8658960
41 + 8658919 = 8658960
67 + 8658893 = 8658960
73 + 8658887 = 8658960
83 + 8658877 = 8658960
113 + 8658847 = 8658960

Showing the first eight; more decompositions exist.
