Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170730, here are decompositions:

19 + 170711 = 170730
23 + 170707 = 170730
29 + 170701 = 170730
41 + 170689 = 170730
61 + 170669 = 170730
83 + 170647 = 170730
89 + 170641 = 170730
97 + 170633 = 170730

Showing the first eight; more decompositions exist.
