Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25798, here are decompositions:

5 + 25793 = 25798
131 + 25667 = 25798
197 + 25601 = 25798
257 + 25541 = 25798
359 + 25439 = 25798
389 + 25409 = 25798
431 + 25367 = 25798
449 + 25349 = 25798

Showing the first eight; more decompositions exist.
