Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23978, here are decompositions:

7 + 23971 = 23978
61 + 23917 = 23978
67 + 23911 = 23978
79 + 23899 = 23978
109 + 23869 = 23978
151 + 23827 = 23978
211 + 23767 = 23978
307 + 23671 = 23978

Showing the first eight; more decompositions exist.
