Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25438, here are decompositions:

29 + 25409 = 25438
47 + 25391 = 25438
71 + 25367 = 25438
89 + 25349 = 25438
131 + 25307 = 25438
137 + 25301 = 25438
191 + 25247 = 25438
269 + 25169 = 25438

Showing the first eight; more decompositions exist.
