Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667912, here are decompositions:

5 + 8667907 = 8667912
13 + 8667899 = 8667912
41 + 8667871 = 8667912
83 + 8667829 = 8667912
103 + 8667809 = 8667912
179 + 8667733 = 8667912
191 + 8667721 = 8667912
223 + 8667689 = 8667912

Showing the first eight; more decompositions exist.
