Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667618, here are decompositions:

5 + 8667613 = 8667618
7 + 8667611 = 8667618
17 + 8667601 = 8667618
59 + 8667559 = 8667618
79 + 8667539 = 8667618
97 + 8667521 = 8667618
107 + 8667511 = 8667618
191 + 8667427 = 8667618

Showing the first eight; more decompositions exist.
