Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616020, here are decompositions:

31 + 8615989 = 8616020
37 + 8615983 = 8616020
79 + 8615941 = 8616020
103 + 8615917 = 8616020
139 + 8615881 = 8616020
211 + 8615809 = 8616020
229 + 8615791 = 8616020
271 + 8615749 = 8616020

Showing the first eight; more decompositions exist.
