Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678958, here are decompositions:

7 + 8678951 = 8678958
11 + 8678947 = 8678958
17 + 8678941 = 8678958
19 + 8678939 = 8678958
31 + 8678927 = 8678958
59 + 8678899 = 8678958
107 + 8678851 = 8678958
137 + 8678821 = 8678958

Showing the first eight; more decompositions exist.
