Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661958, here are decompositions:

5 + 8661953 = 8661958
17 + 8661941 = 8661958
59 + 8661899 = 8661958
191 + 8661767 = 8661958
251 + 8661707 = 8661958
269 + 8661689 = 8661958
317 + 8661641 = 8661958
401 + 8661557 = 8661958

Showing the first eight; more decompositions exist.
