Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171390, here are decompositions:

7 + 171383 = 171390
61 + 171329 = 171390
73 + 171317 = 171390
97 + 171293 = 171390
127 + 171263 = 171390
137 + 171253 = 171390
139 + 171251 = 171390
157 + 171233 = 171390

Showing the first eight; more decompositions exist.
