Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11790, here are decompositions:

7 + 11783 = 11790
11 + 11779 = 11790
13 + 11777 = 11790
47 + 11743 = 11790
59 + 11731 = 11790
71 + 11719 = 11790
73 + 11717 = 11790
89 + 11701 = 11790

Showing the first eight; more decompositions exist.
