Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20298, here are decompositions:

11 + 20287 = 20298
29 + 20269 = 20298
37 + 20261 = 20298
67 + 20231 = 20298
79 + 20219 = 20298
97 + 20201 = 20298
137 + 20161 = 20298
149 + 20149 = 20298

Showing the first eight; more decompositions exist.
