Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171738, here are decompositions:

5 + 171733 = 171738
19 + 171719 = 171738
31 + 171707 = 171738
41 + 171697 = 171738
59 + 171679 = 171738
67 + 171671 = 171738
79 + 171659 = 171738
97 + 171641 = 171738

Showing the first eight; more decompositions exist.
