Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25870, here are decompositions:

3 + 25867 = 25870
23 + 25847 = 25870
29 + 25841 = 25870
71 + 25799 = 25870
107 + 25763 = 25870
137 + 25733 = 25870
167 + 25703 = 25870
191 + 25679 = 25870

Showing the first eight; more decompositions exist.
