Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628080, here are decompositions:

3 + 8628077 = 8628080
31 + 8628049 = 8628080
61 + 8628019 = 8628080
73 + 8628007 = 8628080
103 + 8627977 = 8628080
127 + 8627953 = 8628080
229 + 8627851 = 8628080
271 + 8627809 = 8628080

Showing the first eight; more decompositions exist.
