Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047780, here are decompositions:

7 + 1047773 = 1047780
17 + 1047763 = 1047780
29 + 1047751 = 1047780
43 + 1047737 = 1047780
59 + 1047721 = 1047780
67 + 1047713 = 1047780
79 + 1047701 = 1047780
89 + 1047691 = 1047780

Showing the first eight; more decompositions exist.
