Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998288, here are decompositions:

7 + 998281 = 998288
127 + 998161 = 998288
211 + 998077 = 998288
271 + 998017 = 998288
397 + 997891 = 998288
409 + 997879 = 998288
547 + 997741 = 998288
607 + 997681 = 998288

Showing the first eight; more decompositions exist.
