Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998128, here are decompositions:

11 + 998117 = 998128
17 + 998111 = 998128
59 + 998069 = 998128
101 + 998027 = 998128
137 + 997991 = 998128
167 + 997961 = 998128
179 + 997949 = 998128
239 + 997889 = 998128

Showing the first eight; more decompositions exist.
