Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668086, here are decompositions:

5 + 8668081 = 8668086
13 + 8668073 = 8668086
19 + 8668067 = 8668086
23 + 8668063 = 8668086
29 + 8668057 = 8668086
43 + 8668043 = 8668086
107 + 8667979 = 8668086
113 + 8667973 = 8668086

Showing the first eight; more decompositions exist.
