Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649858, here are decompositions:

5 + 8649853 = 8649858
11 + 8649847 = 8649858
67 + 8649791 = 8649858
97 + 8649761 = 8649858
101 + 8649757 = 8649858
137 + 8649721 = 8649858
167 + 8649691 = 8649858
181 + 8649677 = 8649858

Showing the first eight; more decompositions exist.
