Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101206, here are decompositions:

3 + 101203 = 101206
23 + 101183 = 101206
47 + 101159 = 101206
89 + 101117 = 101206
179 + 101027 = 101206
197 + 101009 = 101206
263 + 100943 = 101206
269 + 100937 = 101206

Showing the first eight; more decompositions exist.
