Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998198, here are decompositions:

31 + 998167 = 998198
37 + 998161 = 998198
127 + 998071 = 998198
181 + 998017 = 998198
307 + 997891 = 998198
457 + 997741 = 998198
499 + 997699 = 998198
547 + 997651 = 998198

Showing the first eight; more decompositions exist.
