Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616080, here are decompositions:

37 + 8616043 = 8616080
43 + 8616037 = 8616080
61 + 8616019 = 8616080
97 + 8615983 = 8616080
139 + 8615941 = 8616080
163 + 8615917 = 8616080
199 + 8615881 = 8616080
271 + 8615809 = 8616080

Showing the first eight; more decompositions exist.
