Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168290, here are decompositions:

13 + 168277 = 168290
37 + 168253 = 168290
43 + 168247 = 168290
79 + 168211 = 168290
97 + 168193 = 168290
139 + 168151 = 168290
163 + 168127 = 168290
181 + 168109 = 168290

Showing the first eight; more decompositions exist.
