Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007778, here are decompositions:

7 + 1007771 = 1007778
11 + 1007767 = 1007778
19 + 1007759 = 1007778
29 + 1007749 = 1007778
47 + 1007731 = 1007778
59 + 1007719 = 1007778
67 + 1007711 = 1007778
97 + 1007681 = 1007778

Showing the first eight; more decompositions exist.
