Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667834, here are decompositions:

5 + 8667829 = 8667834
13 + 8667821 = 8667834
37 + 8667797 = 8667834
41 + 8667793 = 8667834
101 + 8667733 = 8667834
107 + 8667727 = 8667834
113 + 8667721 = 8667834
127 + 8667707 = 8667834

Showing the first eight; more decompositions exist.
