Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998118, here are decompositions:

7 + 998111 = 998118
41 + 998077 = 998118
47 + 998071 = 998118
89 + 998029 = 998118
101 + 998017 = 998118
109 + 998009 = 998118
127 + 997991 = 998118
157 + 997961 = 998118

Showing the first eight; more decompositions exist.
