Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123208, here are decompositions:

5 + 123203 = 123208
17 + 123191 = 123208
131 + 123077 = 123208
149 + 123059 = 123208
191 + 123017 = 123208
251 + 122957 = 123208
269 + 122939 = 123208
317 + 122891 = 123208

Showing the first eight; more decompositions exist.
