Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25436, here are decompositions:

13 + 25423 = 25436
79 + 25357 = 25436
97 + 25339 = 25436
127 + 25309 = 25436
193 + 25243 = 25436
199 + 25237 = 25436
283 + 25153 = 25436
349 + 25087 = 25436

Showing the first eight; more decompositions exist.
