Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171402, here are decompositions:

19 + 171383 = 171402
61 + 171341 = 171402
73 + 171329 = 171402
103 + 171299 = 171402
109 + 171293 = 171402
131 + 171271 = 171402
139 + 171263 = 171402
149 + 171253 = 171402

Showing the first eight; more decompositions exist.
