Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25802, here are decompositions:

3 + 25799 = 25802
31 + 25771 = 25802
43 + 25759 = 25802
61 + 25741 = 25802
109 + 25693 = 25802
163 + 25639 = 25802
181 + 25621 = 25802
193 + 25609 = 25802

Showing the first eight; more decompositions exist.
