Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4128, here are decompositions:

17 + 4111 = 4128
29 + 4099 = 4128
37 + 4091 = 4128
71 + 4057 = 4128
79 + 4049 = 4128
101 + 4027 = 4128
107 + 4021 = 4128
109 + 4019 = 4128

Showing the first eight; more decompositions exist.
