Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171456, here are decompositions:

7 + 171449 = 171456
17 + 171439 = 171456
29 + 171427 = 171456
53 + 171403 = 171456
73 + 171383 = 171456
127 + 171329 = 171456
139 + 171317 = 171456
157 + 171299 = 171456

Showing the first eight; more decompositions exist.
