Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23820, here are decompositions:

7 + 23813 = 23820
19 + 23801 = 23820
31 + 23789 = 23820
47 + 23773 = 23820
53 + 23767 = 23820
59 + 23761 = 23820
67 + 23753 = 23820
73 + 23747 = 23820

Showing the first eight; more decompositions exist.
