Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80790, here are decompositions:

7 + 80783 = 80790
11 + 80779 = 80790
13 + 80777 = 80790
29 + 80761 = 80790
41 + 80749 = 80790
43 + 80747 = 80790
53 + 80737 = 80790
89 + 80701 = 80790

Showing the first eight; more decompositions exist.
