Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4102, here are decompositions:

3 + 4099 = 4102
11 + 4091 = 4102
23 + 4079 = 4102
29 + 4073 = 4102
53 + 4049 = 4102
83 + 4019 = 4102
89 + 4013 = 4102
101 + 4001 = 4102

Showing the first eight; more decompositions exist.
