Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028778, here are decompositions:

5 + 1028773 = 1028778
17 + 1028761 = 1028778
29 + 1028749 = 1028778
31 + 1028747 = 1028778
41 + 1028737 = 1028778
97 + 1028681 = 1028778
109 + 1028669 = 1028778
131 + 1028647 = 1028778

Showing the first eight; more decompositions exist.
