Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25582, here are decompositions:

3 + 25579 = 25582
5 + 25577 = 25582
41 + 25541 = 25582
59 + 25523 = 25582
113 + 25469 = 25582
173 + 25409 = 25582
191 + 25391 = 25582
233 + 25349 = 25582

Showing the first eight; more decompositions exist.
