Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28408, here are decompositions:

5 + 28403 = 28408
59 + 28349 = 28408
89 + 28319 = 28408
101 + 28307 = 28408
131 + 28277 = 28408
179 + 28229 = 28408
197 + 28211 = 28408
227 + 28181 = 28408

Showing the first eight; more decompositions exist.
