Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28470, here are decompositions:

7 + 28463 = 28470
23 + 28447 = 28470
31 + 28439 = 28470
37 + 28433 = 28470
41 + 28429 = 28470
59 + 28411 = 28470
61 + 28409 = 28470
67 + 28403 = 28470

Showing the first eight; more decompositions exist.
