Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8790, here are decompositions:

7 + 8783 = 8790
11 + 8779 = 8790
29 + 8761 = 8790
37 + 8753 = 8790
43 + 8747 = 8790
53 + 8737 = 8790
59 + 8731 = 8790
71 + 8719 = 8790

Showing the first eight; more decompositions exist.
