Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028972, here are decompositions:

3 + 1028969 = 1028972
19 + 1028953 = 1028972
31 + 1028941 = 1028972
79 + 1028893 = 1028972
163 + 1028809 = 1028972
199 + 1028773 = 1028972
211 + 1028761 = 1028972
223 + 1028749 = 1028972

Showing the first eight; more decompositions exist.
