Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23870, here are decompositions:

13 + 23857 = 23870
37 + 23833 = 23870
43 + 23827 = 23870
97 + 23773 = 23870
103 + 23767 = 23870
109 + 23761 = 23870
127 + 23743 = 23870
151 + 23719 = 23870

Showing the first eight; more decompositions exist.
