Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998286, here are decompositions:

5 + 998281 = 998286
13 + 998273 = 998286
43 + 998243 = 998286
67 + 998219 = 998286
73 + 998213 = 998286
89 + 998197 = 998286
139 + 998147 = 998286
257 + 998029 = 998286

Showing the first eight; more decompositions exist.
