Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27490, here are decompositions:

3 + 27487 = 27490
11 + 27479 = 27490
41 + 27449 = 27490
53 + 27437 = 27490
59 + 27431 = 27490
83 + 27407 = 27490
191 + 27299 = 27490
251 + 27239 = 27490

Showing the first eight; more decompositions exist.
