Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171278, here are decompositions:

7 + 171271 = 171278
109 + 171169 = 171278
199 + 171079 = 171278
229 + 171049 = 171278
271 + 171007 = 171278
307 + 170971 = 171278
379 + 170899 = 171278
397 + 170881 = 171278

Showing the first eight; more decompositions exist.
