Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26290, here are decompositions:

23 + 26267 = 26290
29 + 26261 = 26290
41 + 26249 = 26290
53 + 26237 = 26290
101 + 26189 = 26290
107 + 26183 = 26290
113 + 26177 = 26290
137 + 26153 = 26290

Showing the first eight; more decompositions exist.
