Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998536, here are decompositions:

23 + 998513 = 998536
107 + 998429 = 998536
113 + 998423 = 998536
137 + 998399 = 998536
263 + 998273 = 998536
293 + 998243 = 998536
317 + 998219 = 998536
389 + 998147 = 998536

Showing the first eight; more decompositions exist.
