Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171742, here are decompositions:

23 + 171719 = 171742
29 + 171713 = 171742
71 + 171671 = 171742
83 + 171659 = 171742
89 + 171653 = 171742
101 + 171641 = 171742
113 + 171629 = 171742
251 + 171491 = 171742

Showing the first eight; more decompositions exist.
