Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28204, here are decompositions:

3 + 28201 = 28204
23 + 28181 = 28204
41 + 28163 = 28204
53 + 28151 = 28204
107 + 28097 = 28204
173 + 28031 = 28204
251 + 27953 = 28204
257 + 27947 = 28204

Showing the first eight; more decompositions exist.
