Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123808, here are decompositions:

5 + 123803 = 123808
17 + 123791 = 123808
71 + 123737 = 123808
89 + 123719 = 123808
101 + 123707 = 123808
107 + 123701 = 123808
131 + 123677 = 123808
227 + 123581 = 123808

Showing the first eight; more decompositions exist.
