Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169208, here are decompositions:

31 + 169177 = 169208
79 + 169129 = 169208
97 + 169111 = 169208
139 + 169069 = 169208
199 + 169009 = 169208
271 + 168937 = 169208
307 + 168901 = 169208
439 + 168769 = 169208

Showing the first eight; more decompositions exist.
