Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23878, here are decompositions:

5 + 23873 = 23878
47 + 23831 = 23878
59 + 23819 = 23878
89 + 23789 = 23878
131 + 23747 = 23878
137 + 23741 = 23878
191 + 23687 = 23878
251 + 23627 = 23878

Showing the first eight; more decompositions exist.
