Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25766, here are decompositions:

3 + 25763 = 25766
7 + 25759 = 25766
19 + 25747 = 25766
73 + 25693 = 25766
109 + 25657 = 25766
127 + 25639 = 25766
157 + 25609 = 25766
163 + 25603 = 25766

Showing the first eight; more decompositions exist.
