Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25688, here are decompositions:

31 + 25657 = 25688
67 + 25621 = 25688
79 + 25609 = 25688
109 + 25579 = 25688
127 + 25561 = 25688
151 + 25537 = 25688
241 + 25447 = 25688
277 + 25411 = 25688

Showing the first eight; more decompositions exist.
