Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168450, here are decompositions:

17 + 168433 = 168450
41 + 168409 = 168450
59 + 168391 = 168450
97 + 168353 = 168450
103 + 168347 = 168450
127 + 168323 = 168450
157 + 168293 = 168450
173 + 168277 = 168450

Showing the first eight; more decompositions exist.
