Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646790, here are decompositions:

11 + 8646779 = 8646790
71 + 8646719 = 8646790
83 + 8646707 = 8646790
107 + 8646683 = 8646790
293 + 8646497 = 8646790
311 + 8646479 = 8646790
389 + 8646401 = 8646790
401 + 8646389 = 8646790

Showing the first eight; more decompositions exist.
