Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28382, here are decompositions:

31 + 28351 = 28382
73 + 28309 = 28382
103 + 28279 = 28382
163 + 28219 = 28382
181 + 28201 = 28382
199 + 28183 = 28382
271 + 28111 = 28382
283 + 28099 = 28382

Showing the first eight; more decompositions exist.
