Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998566, here are decompositions:

5 + 998561 = 998566
29 + 998537 = 998566
53 + 998513 = 998566
137 + 998429 = 998566
167 + 998399 = 998566
293 + 998273 = 998566
347 + 998219 = 998566
353 + 998213 = 998566

Showing the first eight; more decompositions exist.
