Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649958, here are decompositions:

29 + 8649929 = 8649958
47 + 8649911 = 8649958
71 + 8649887 = 8649958
89 + 8649869 = 8649958
101 + 8649857 = 8649958
167 + 8649791 = 8649958
197 + 8649761 = 8649958
269 + 8649689 = 8649958

Showing the first eight; more decompositions exist.
