Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998788, here are decompositions:

29 + 998759 = 998788
71 + 998717 = 998788
101 + 998687 = 998788
107 + 998681 = 998788
137 + 998651 = 998788
227 + 998561 = 998788
251 + 998537 = 998788
317 + 998471 = 998788

Showing the first eight; more decompositions exist.
