Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25756, here are decompositions:

23 + 25733 = 25756
53 + 25703 = 25756
83 + 25673 = 25756
89 + 25667 = 25756
113 + 25643 = 25756
167 + 25589 = 25756
173 + 25583 = 25756
179 + 25577 = 25756

Showing the first eight; more decompositions exist.
