Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28394, here are decompositions:

7 + 28387 = 28394
43 + 28351 = 28394
97 + 28297 = 28394
193 + 28201 = 28394
211 + 28183 = 28394
271 + 28123 = 28394
283 + 28111 = 28394
307 + 28087 = 28394

Showing the first eight; more decompositions exist.
