Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28282, here are decompositions:

3 + 28279 = 28282
5 + 28277 = 28282
53 + 28229 = 28282
71 + 28211 = 28282
101 + 28181 = 28282
131 + 28151 = 28282
173 + 28109 = 28282
251 + 28031 = 28282

Showing the first eight; more decompositions exist.
