Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25558, here are decompositions:

17 + 25541 = 25558
89 + 25469 = 25558
101 + 25457 = 25558
149 + 25409 = 25558
167 + 25391 = 25558
191 + 25367 = 25558
251 + 25307 = 25558
257 + 25301 = 25558

Showing the first eight; more decompositions exist.
