Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998218, here are decompositions:

5 + 998213 = 998218
17 + 998201 = 998218
71 + 998147 = 998218
101 + 998117 = 998218
107 + 998111 = 998218
149 + 998069 = 998218
191 + 998027 = 998218
227 + 997991 = 998218

Showing the first eight; more decompositions exist.
