Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998556, here are decompositions:

5 + 998551 = 998556
17 + 998539 = 998556
19 + 998537 = 998556
29 + 998527 = 998556
43 + 998513 = 998556
59 + 998497 = 998556
113 + 998443 = 998556
127 + 998429 = 998556

Showing the first eight; more decompositions exist.
