Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20248, here are decompositions:

17 + 20231 = 20248
29 + 20219 = 20248
47 + 20201 = 20248
71 + 20177 = 20248
101 + 20147 = 20248
131 + 20117 = 20248
197 + 20051 = 20248
227 + 20021 = 20248

Showing the first eight; more decompositions exist.
