Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25662, here are decompositions:

5 + 25657 = 25662
19 + 25643 = 25662
23 + 25639 = 25662
29 + 25633 = 25662
41 + 25621 = 25662
53 + 25609 = 25662
59 + 25603 = 25662
61 + 25601 = 25662

Showing the first eight; more decompositions exist.
