Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25776, here are decompositions:

5 + 25771 = 25776
13 + 25763 = 25776
17 + 25759 = 25776
29 + 25747 = 25776
43 + 25733 = 25776
59 + 25717 = 25776
73 + 25703 = 25776
83 + 25693 = 25776

Showing the first eight; more decompositions exist.
