Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25782, here are decompositions:

11 + 25771 = 25782
19 + 25763 = 25782
23 + 25759 = 25782
41 + 25741 = 25782
79 + 25703 = 25782
89 + 25693 = 25782
103 + 25679 = 25782
109 + 25673 = 25782

Showing the first eight; more decompositions exist.
