Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998728, here are decompositions:

11 + 998717 = 998728
41 + 998687 = 998728
47 + 998681 = 998728
167 + 998561 = 998728
191 + 998537 = 998728
257 + 998471 = 998728
317 + 998411 = 998728
347 + 998381 = 998728

Showing the first eight; more decompositions exist.
