Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998154, here are decompositions:

7 + 998147 = 998154
37 + 998117 = 998154
43 + 998111 = 998154
71 + 998083 = 998154
83 + 998071 = 998154
127 + 998027 = 998154
137 + 998017 = 998154
163 + 997991 = 998154

Showing the first eight; more decompositions exist.
