Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26490, here are decompositions:

11 + 26479 = 26490
31 + 26459 = 26490
41 + 26449 = 26490
53 + 26437 = 26490
59 + 26431 = 26490
67 + 26423 = 26490
73 + 26417 = 26490
83 + 26407 = 26490

Showing the first eight; more decompositions exist.
