Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25906, here are decompositions:

3 + 25903 = 25906
17 + 25889 = 25906
59 + 25847 = 25906
107 + 25799 = 25906
113 + 25793 = 25906
173 + 25733 = 25906
227 + 25679 = 25906
233 + 25673 = 25906

Showing the first eight; more decompositions exist.
