Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171208, here are decompositions:

5 + 171203 = 171208
29 + 171179 = 171208
41 + 171167 = 171208
47 + 171161 = 171208
131 + 171077 = 171208
179 + 171029 = 171208
251 + 170957 = 171208
281 + 170927 = 171208

Showing the first eight; more decompositions exist.
