Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615928, here are decompositions:

11 + 8615917 = 8615928
37 + 8615891 = 8615928
47 + 8615881 = 8615928
137 + 8615791 = 8615928
157 + 8615771 = 8615928
179 + 8615749 = 8615928
271 + 8615657 = 8615928
337 + 8615591 = 8615928

Showing the first eight; more decompositions exist.
