Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1017128, here are decompositions:

31 + 1017097 = 1017128
67 + 1017061 = 1017128
97 + 1017031 = 1017128
157 + 1016971 = 1017128
181 + 1016947 = 1017128
199 + 1016929 = 1017128
379 + 1016749 = 1017128
397 + 1016731 = 1017128

Showing the first eight; more decompositions exist.
