Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25804, here are decompositions:

3 + 25801 = 25804
5 + 25799 = 25804
11 + 25793 = 25804
41 + 25763 = 25804
71 + 25733 = 25804
101 + 25703 = 25804
131 + 25673 = 25804
137 + 25667 = 25804

Showing the first eight; more decompositions exist.
