Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998158, here are decompositions:

11 + 998147 = 998158
41 + 998117 = 998158
47 + 998111 = 998158
89 + 998069 = 998158
131 + 998027 = 998158
149 + 998009 = 998158
167 + 997991 = 998158
197 + 997961 = 998158

Showing the first eight; more decompositions exist.
