Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998518, here are decompositions:

5 + 998513 = 998518
47 + 998471 = 998518
89 + 998429 = 998518
107 + 998411 = 998518
137 + 998381 = 998518
281 + 998237 = 998518
317 + 998201 = 998518
401 + 998117 = 998518

Showing the first eight; more decompositions exist.
