Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 24138, here are decompositions:

5 + 24133 = 24138
17 + 24121 = 24138
29 + 24109 = 24138
31 + 24107 = 24138
41 + 24097 = 24138
47 + 24091 = 24138
61 + 24077 = 24138
67 + 24071 = 24138

Showing the first eight; more decompositions exist.
