Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171478, here are decompositions:

5 + 171473 = 171478
11 + 171467 = 171478
29 + 171449 = 171478
137 + 171341 = 171478
149 + 171329 = 171478
179 + 171299 = 171478
227 + 171251 = 171478
311 + 171167 = 171478

Showing the first eight; more decompositions exist.
