Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667968, here are decompositions:

7 + 8667961 = 8667968
19 + 8667949 = 8667968
37 + 8667931 = 8667968
61 + 8667907 = 8667968
97 + 8667871 = 8667968
139 + 8667829 = 8667968
241 + 8667727 = 8667968
271 + 8667697 = 8667968

Showing the first eight; more decompositions exist.
