Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998190, here are decompositions:

23 + 998167 = 998190
29 + 998161 = 998190
43 + 998147 = 998190
73 + 998117 = 998190
79 + 998111 = 998190
107 + 998083 = 998190
113 + 998077 = 998190
163 + 998027 = 998190

Showing the first eight; more decompositions exist.
