Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26780, here are decompositions:

3 + 26777 = 26780
43 + 26737 = 26780
67 + 26713 = 26780
79 + 26701 = 26780
97 + 26683 = 26780
139 + 26641 = 26780
223 + 26557 = 26780
241 + 26539 = 26780

Showing the first eight; more decompositions exist.
