Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25788, here are decompositions:

17 + 25771 = 25788
29 + 25759 = 25788
41 + 25747 = 25788
47 + 25741 = 25788
71 + 25717 = 25788
109 + 25679 = 25788
131 + 25657 = 25788
149 + 25639 = 25788

Showing the first eight; more decompositions exist.
