Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28292, here are decompositions:

3 + 28289 = 28292
13 + 28279 = 28292
73 + 28219 = 28292
109 + 28183 = 28292
181 + 28111 = 28292
193 + 28099 = 28292
211 + 28081 = 28292
223 + 28069 = 28292

Showing the first eight; more decompositions exist.
