Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998178, here are decompositions:

11 + 998167 = 998178
17 + 998161 = 998178
31 + 998147 = 998178
61 + 998117 = 998178
67 + 998111 = 998178
101 + 998077 = 998178
107 + 998071 = 998178
109 + 998069 = 998178

Showing the first eight; more decompositions exist.
