Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25648, here are decompositions:

5 + 25643 = 25648
47 + 25601 = 25648
59 + 25589 = 25648
71 + 25577 = 25648
107 + 25541 = 25648
179 + 25469 = 25648
191 + 25457 = 25648
239 + 25409 = 25648

Showing the first eight; more decompositions exist.
