Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25630, here are decompositions:

29 + 25601 = 25630
41 + 25589 = 25630
47 + 25583 = 25630
53 + 25577 = 25630
89 + 25541 = 25630
107 + 25523 = 25630
167 + 25463 = 25630
173 + 25457 = 25630

Showing the first eight; more decompositions exist.
