Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25786, here are decompositions:

23 + 25763 = 25786
53 + 25733 = 25786
83 + 25703 = 25786
107 + 25679 = 25786
113 + 25673 = 25786
197 + 25589 = 25786
263 + 25523 = 25786
317 + 25469 = 25786

Showing the first eight; more decompositions exist.
