Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123206, here are decompositions:

3 + 123203 = 123206
37 + 123169 = 123206
79 + 123127 = 123206
157 + 123049 = 123206
199 + 123007 = 123206
277 + 122929 = 123206
337 + 122869 = 123206
367 + 122839 = 123206

Showing the first eight; more decompositions exist.
