Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25620, here are decompositions:

11 + 25609 = 25620
17 + 25603 = 25620
19 + 25601 = 25620
31 + 25589 = 25620
37 + 25583 = 25620
41 + 25579 = 25620
43 + 25577 = 25620
59 + 25561 = 25620

Showing the first eight; more decompositions exist.
