Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667740, here are decompositions:

7 + 8667733 = 8667740
13 + 8667727 = 8667740
19 + 8667721 = 8667740
43 + 8667697 = 8667740
79 + 8667661 = 8667740
127 + 8667613 = 8667740
139 + 8667601 = 8667740
181 + 8667559 = 8667740

Showing the first eight; more decompositions exist.
