Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171042, here are decompositions:

13 + 171029 = 171042
19 + 171023 = 171042
71 + 170971 = 171042
89 + 170953 = 171042
191 + 170851 = 171042
199 + 170843 = 171042
229 + 170813 = 171042
233 + 170809 = 171042

Showing the first eight; more decompositions exist.
