Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25420, here are decompositions:

11 + 25409 = 25420
29 + 25391 = 25420
47 + 25373 = 25420
53 + 25367 = 25420
71 + 25349 = 25420
113 + 25307 = 25420
167 + 25253 = 25420
173 + 25247 = 25420

Showing the first eight; more decompositions exist.
