Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171420, here are decompositions:

17 + 171403 = 171420
19 + 171401 = 171420
37 + 171383 = 171420
79 + 171341 = 171420
103 + 171317 = 171420
127 + 171293 = 171420
149 + 171271 = 171420
157 + 171263 = 171420

Showing the first eight; more decompositions exist.
