Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668080, here are decompositions:

7 + 8668073 = 8668080
13 + 8668067 = 8668080
17 + 8668063 = 8668080
19 + 8668061 = 8668080
23 + 8668057 = 8668080
37 + 8668043 = 8668080
79 + 8668001 = 8668080
101 + 8667979 = 8668080

Showing the first eight; more decompositions exist.
