Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28502, here are decompositions:

3 + 28499 = 28502
73 + 28429 = 28502
109 + 28393 = 28502
151 + 28351 = 28502
193 + 28309 = 28502
223 + 28279 = 28502
283 + 28219 = 28502
379 + 28123 = 28502

Showing the first eight; more decompositions exist.
