Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25764, here are decompositions:

5 + 25759 = 25764
17 + 25747 = 25764
23 + 25741 = 25764
31 + 25733 = 25764
47 + 25717 = 25764
61 + 25703 = 25764
71 + 25693 = 25764
97 + 25667 = 25764

Showing the first eight; more decompositions exist.
