Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667738, here are decompositions:

5 + 8667733 = 8667738
11 + 8667727 = 8667738
17 + 8667721 = 8667738
31 + 8667707 = 8667738
41 + 8667697 = 8667738
61 + 8667677 = 8667738
97 + 8667641 = 8667738
127 + 8667611 = 8667738

Showing the first eight; more decompositions exist.
