Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171448, here are decompositions:

47 + 171401 = 171448
107 + 171341 = 171448
131 + 171317 = 171448
149 + 171299 = 171448
197 + 171251 = 171448
269 + 171179 = 171448
281 + 171167 = 171448
317 + 171131 = 171448

Showing the first eight; more decompositions exist.
