Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171684, here are decompositions:

5 + 171679 = 171684
11 + 171673 = 171684
13 + 171671 = 171684
31 + 171653 = 171684
43 + 171641 = 171684
47 + 171637 = 171684
67 + 171617 = 171684
101 + 171583 = 171684

Showing the first eight; more decompositions exist.
