Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023198, here are decompositions:

31 + 1023167 = 1023198
97 + 1023101 = 1023198
131 + 1023067 = 1023198
151 + 1023047 = 1023198
157 + 1023041 = 1023198
179 + 1023019 = 1023198
269 + 1022929 = 1023198
307 + 1022891 = 1023198

Showing the first eight; more decompositions exist.
