Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102206, here are decompositions:

3 + 102203 = 102206
7 + 102199 = 102206
67 + 102139 = 102206
103 + 102103 = 102206
127 + 102079 = 102206
163 + 102043 = 102206
193 + 102013 = 102206
229 + 101977 = 102206

Showing the first eight; more decompositions exist.
