Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10206, here are decompositions:

13 + 10193 = 10206
29 + 10177 = 10206
37 + 10169 = 10206
43 + 10163 = 10206
47 + 10159 = 10206
67 + 10139 = 10206
73 + 10133 = 10206
103 + 10103 = 10206

Showing the first eight; more decompositions exist.
