Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28492, here are decompositions:

29 + 28463 = 28492
53 + 28439 = 28492
59 + 28433 = 28492
83 + 28409 = 28492
89 + 28403 = 28492
173 + 28319 = 28492
263 + 28229 = 28492
281 + 28211 = 28492

Showing the first eight; more decompositions exist.
