Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171238, here are decompositions:

5 + 171233 = 171238
59 + 171179 = 171238
71 + 171167 = 171238
107 + 171131 = 171238
191 + 171047 = 171238
281 + 170957 = 171238
311 + 170927 = 171238
317 + 170921 = 171238

Showing the first eight; more decompositions exist.
