Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25770, here are decompositions:

7 + 25763 = 25770
11 + 25759 = 25770
23 + 25747 = 25770
29 + 25741 = 25770
37 + 25733 = 25770
53 + 25717 = 25770
67 + 25703 = 25770
97 + 25673 = 25770

Showing the first eight; more decompositions exist.
