Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25930, here are decompositions:

11 + 25919 = 25930
17 + 25913 = 25930
41 + 25889 = 25930
83 + 25847 = 25930
89 + 25841 = 25930
131 + 25799 = 25930
137 + 25793 = 25930
167 + 25763 = 25930

Showing the first eight; more decompositions exist.
