Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25738, here are decompositions:

5 + 25733 = 25738
59 + 25679 = 25738
71 + 25667 = 25738
137 + 25601 = 25738
149 + 25589 = 25738
197 + 25541 = 25738
269 + 25469 = 25738
281 + 25457 = 25738

Showing the first eight; more decompositions exist.
