Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25910, here are decompositions:

7 + 25903 = 25910
37 + 25873 = 25910
43 + 25867 = 25910
61 + 25849 = 25910
109 + 25801 = 25910
139 + 25771 = 25910
151 + 25759 = 25910
163 + 25747 = 25910

Showing the first eight; more decompositions exist.
