Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667726, here are decompositions:

5 + 8667721 = 8667726
19 + 8667707 = 8667726
29 + 8667697 = 8667726
37 + 8667689 = 8667726
73 + 8667653 = 8667726
113 + 8667613 = 8667726
163 + 8667563 = 8667726
167 + 8667559 = 8667726

Showing the first eight; more decompositions exist.
