Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25586, here are decompositions:

3 + 25583 = 25586
7 + 25579 = 25586
139 + 25447 = 25586
163 + 25423 = 25586
229 + 25357 = 25586
277 + 25309 = 25586
283 + 25303 = 25586
349 + 25237 = 25586

Showing the first eight; more decompositions exist.
