Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171690, here are decompositions:

11 + 171679 = 171690
17 + 171673 = 171690
19 + 171671 = 171690
31 + 171659 = 171690
37 + 171653 = 171690
53 + 171637 = 171690
61 + 171629 = 171690
73 + 171617 = 171690

Showing the first eight; more decompositions exist.
