Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20254, here are decompositions:

5 + 20249 = 20254
23 + 20231 = 20254
53 + 20201 = 20254
71 + 20183 = 20254
107 + 20147 = 20254
131 + 20123 = 20254
137 + 20117 = 20254
191 + 20063 = 20254

Showing the first eight; more decompositions exist.
