Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25678, here are decompositions:

5 + 25673 = 25678
11 + 25667 = 25678
89 + 25589 = 25678
101 + 25577 = 25678
137 + 25541 = 25678
239 + 25439 = 25678
269 + 25409 = 25678
311 + 25367 = 25678

Showing the first eight; more decompositions exist.
