Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171830, here are decompositions:

3 + 171827 = 171830
7 + 171823 = 171830
19 + 171811 = 171830
31 + 171799 = 171830
37 + 171793 = 171830
67 + 171763 = 171830
73 + 171757 = 171830
97 + 171733 = 171830

Showing the first eight; more decompositions exist.
