Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171438, here are decompositions:

11 + 171427 = 171438
37 + 171401 = 171438
97 + 171341 = 171438
109 + 171329 = 171438
139 + 171299 = 171438
167 + 171271 = 171438
269 + 171169 = 171438
271 + 171167 = 171438

Showing the first eight; more decompositions exist.
