Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23780, here are decompositions:

7 + 23773 = 23780
13 + 23767 = 23780
19 + 23761 = 23780
37 + 23743 = 23780
61 + 23719 = 23780
103 + 23677 = 23780
109 + 23671 = 23780
151 + 23629 = 23780

Showing the first eight; more decompositions exist.
