Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639790, here are decompositions:

11 + 8639779 = 8639790
17 + 8639773 = 8639790
37 + 8639753 = 8639790
41 + 8639749 = 8639790
43 + 8639747 = 8639790
79 + 8639711 = 8639790
127 + 8639663 = 8639790
151 + 8639639 = 8639790

Showing the first eight; more decompositions exist.
