Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651958, here are decompositions:

5 + 8651953 = 8651958
17 + 8651941 = 8651958
19 + 8651939 = 8651958
41 + 8651917 = 8651958
67 + 8651891 = 8651958
89 + 8651869 = 8651958
101 + 8651857 = 8651958
167 + 8651791 = 8651958

Showing the first eight; more decompositions exist.
