Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28206, here are decompositions:

5 + 28201 = 28206
23 + 28183 = 28206
43 + 28163 = 28206
83 + 28123 = 28206
97 + 28109 = 28206
107 + 28099 = 28206
109 + 28097 = 28206
137 + 28069 = 28206

Showing the first eight; more decompositions exist.
