Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28452, here are decompositions:

5 + 28447 = 28452
13 + 28439 = 28452
19 + 28433 = 28452
23 + 28429 = 28452
41 + 28411 = 28452
43 + 28409 = 28452
59 + 28393 = 28452
101 + 28351 = 28452

Showing the first eight; more decompositions exist.
