Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171848, here are decompositions:

37 + 171811 = 171848
151 + 171697 = 171848
211 + 171637 = 171848
277 + 171571 = 171848
307 + 171541 = 171848
331 + 171517 = 171848
367 + 171481 = 171848
379 + 171469 = 171848

Showing the first eight; more decompositions exist.
