Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171968, here are decompositions:

31 + 171937 = 171968
79 + 171889 = 171968
157 + 171811 = 171968
211 + 171757 = 171968
271 + 171697 = 171968
331 + 171637 = 171968
397 + 171571 = 171968
409 + 171559 = 171968

Showing the first eight; more decompositions exist.
