Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20260, here are decompositions:

11 + 20249 = 20260
29 + 20231 = 20260
41 + 20219 = 20260
59 + 20201 = 20260
83 + 20177 = 20260
113 + 20147 = 20260
131 + 20129 = 20260
137 + 20123 = 20260

Showing the first eight; more decompositions exist.
