Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28450, here are decompositions:

3 + 28447 = 28450
11 + 28439 = 28450
17 + 28433 = 28450
41 + 28409 = 28450
47 + 28403 = 28450
101 + 28349 = 28450
131 + 28319 = 28450
167 + 28283 = 28450

Showing the first eight; more decompositions exist.
