Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616090, here are decompositions:

19 + 8616071 = 8616090
47 + 8616043 = 8616090
53 + 8616037 = 8616090
61 + 8616029 = 8616090
71 + 8616019 = 8616090
79 + 8616011 = 8616090
101 + 8615989 = 8616090
107 + 8615983 = 8616090

Showing the first eight; more decompositions exist.
