Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25958, here are decompositions:

7 + 25951 = 25958
19 + 25939 = 25958
109 + 25849 = 25958
139 + 25819 = 25958
157 + 25801 = 25958
199 + 25759 = 25958
211 + 25747 = 25958
241 + 25717 = 25958

Showing the first eight; more decompositions exist.
