Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171212, here are decompositions:

43 + 171169 = 171212
109 + 171103 = 171212
163 + 171049 = 171212
241 + 170971 = 171212
313 + 170899 = 171212
331 + 170881 = 171212
439 + 170773 = 171212
463 + 170749 = 171212

Showing the first eight; more decompositions exist.
