Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25790, here are decompositions:

19 + 25771 = 25790
31 + 25759 = 25790
43 + 25747 = 25790
73 + 25717 = 25790
97 + 25693 = 25790
151 + 25639 = 25790
157 + 25633 = 25790
181 + 25609 = 25790

Showing the first eight; more decompositions exist.
