Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25710, here are decompositions:

7 + 25703 = 25710
17 + 25693 = 25710
31 + 25679 = 25710
37 + 25673 = 25710
43 + 25667 = 25710
53 + 25657 = 25710
67 + 25643 = 25710
71 + 25639 = 25710

Showing the first eight; more decompositions exist.
