Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23790, here are decompositions:

17 + 23773 = 23790
23 + 23767 = 23790
29 + 23761 = 23790
37 + 23753 = 23790
43 + 23747 = 23790
47 + 23743 = 23790
71 + 23719 = 23790
101 + 23689 = 23790

Showing the first eight; more decompositions exist.
