Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25670, here are decompositions:

3 + 25667 = 25670
13 + 25657 = 25670
31 + 25639 = 25670
37 + 25633 = 25670
61 + 25609 = 25670
67 + 25603 = 25670
109 + 25561 = 25670
199 + 25471 = 25670

Showing the first eight; more decompositions exist.
