Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25680, here are decompositions:

7 + 25673 = 25680
13 + 25667 = 25680
23 + 25657 = 25680
37 + 25643 = 25680
41 + 25639 = 25680
47 + 25633 = 25680
59 + 25621 = 25680
71 + 25609 = 25680

Showing the first eight; more decompositions exist.
