Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25442, here are decompositions:

3 + 25439 = 25442
19 + 25423 = 25442
31 + 25411 = 25442
103 + 25339 = 25442
139 + 25303 = 25442
181 + 25261 = 25442
199 + 25243 = 25442
223 + 25219 = 25442

Showing the first eight; more decompositions exist.
